This commit does two things. One, it converts the return value of the QueueThreadPlanXXX
plan providers from a "ThreadPlan *" to a "lldb::ThreadPlanSP". That was needed to fix
a bug where the ThreadPlanStepInRange wasn't checking with its sub-plans to make sure they
succeed before trying to proceed further. If the sub-plan failed and as a result didn't make
any progress, you could end up retrying the same failing algorithm in an infinite loop.

Huge change to clean up types.
A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.
This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

A couple of small fixes to make core file debugging less noisy.
Don't want about being unable to find a needed objective-c runtime
function when we're core file debugging and can't jit anything
anyway. Don't warn when quitting a debug session on a core file,
the program state can be reconstructed by re-running lldb on the
same core file again.

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.
All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Change the AppleObjCTrampolineHandler to always run all threads when resolving the target of an ObjC method call.
Add a StopOthers method to AppleThreadPlanStepThroughObjCTrampoline, don't rely on the setting in the ThreadPlanToCallFunction, since that
gets pushed too late to determine which threads will continue.

Add "target.process.stop-on-shared-library-events" setting, and make it work.
Add the ability to give breakpoints a "kind" string, and have the StopInfoBreakpoint
print that in the brief description if set. Also print the kind - if set - in the breakpoint
listing.
Give kinds to a bunch of the internal breakpoints.
We were deleting the Mac OS X dynamic loader breakpoint as though the id we had stored away was
a breakpoint site ID, but in fact it was a breakpoint id, so we never actually deleted it. Fixed that.

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.
So I defined a new "lldb::offset_t" which should be used for all file offsets.
After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.
Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

<rdar://problem/12586350>
This commit does three things:
(a) introduces a new notification model for adding/removing/changing modules to a ModuleList, and applies it to the Target's ModuleList, so that we make sure to always trigger the right set of actions
whenever modules come and go in a target. Certain spots in the code still need to "manually" notify the Target for several reasons, so this is a work in progress
(b) adds a new capability to the Platforms: locating a scripting resources associated to a module. A scripting resource is a Python file that can load commands, formatters, ... and any other action
of interest corresponding to the loading of a module. At the moment, this is only implemented on Mac OS X and only for files inside .dSYM bundles - the next step is going to be letting
the frameworks themselves hold their scripting resources. Implementors of platforms for other systems are free to implement "the right thing" for their own worlds
(c) hooking up items (a) and (b) so that targets auto-load the scripting resources as the corresponding modules get loaded in a target. This has a few caveats at the moment:
- the user needs to manually add the .py file to the dSYM (soon, it will also work in the framework itself)
- if two modules with the same name show up during the lifetime of an LLDB session, the second one won't be able to load its scripting resource, but will otherwise work just fine

Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file".
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()
Cleaned up header includes a bit as well.

Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation:
- no setting auto completion
- very manual and error prone way of getting/setting variables
- tons of code duplication
- useless instance names for processes, threads
Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing".

We were accessing the ModuleList in the target without locking it for tasks like
setting breakpoints. That's dangerous, since while we are setting a breakpoint,
the target might hit the dyld load notification, and start removing modules from
the list. This change adds a GetMutex accessor to the ModuleList class, and
uses it whenever we are accessing the target's ModuleList (as returned by GetImages().)

We sometimes need to be able to call functions (via Process::RunThreadPlan) from code run on the private state thread. To do that we have to
spin up a temporary "private state thread" that will respond to events from the lower level process plugins. This check-in should work to do
that, but it is still buggy. However, if you don't call functions on the private state thread, these changes make no difference.
This patch also moves the code in the AppleObjCRuntime step-through-trampoline handler that might call functions (in the case where the debug
server doesn't support the memory allocate/deallocate packet) out to a safe place to do that call.

This fix really needed to happen as a previous fix I had submitted for
calculating symbol sizes made many symbols appear to have zero size since
the function that was calculating the symbol size was calling another function
that would cause the calculation to happen again. This resulted in some symbols
having zero size when they shouldn't. This could then cause infinite stack
traces and many other side affects.

Thread hardening part 3. Now lldb_private::Thread objects have std::weak_ptr
objects for the backlink to the lldb_private::Process. The issues we were
running into before was someone was holding onto a shared pointer to a
lldb_private::Thread for too long, and the lldb_private::Process parent object
would get destroyed and the lldb_private::Thread had a "Process &m_process"
member which would just treat whatever memory that used to be a Process as a
valid Process. This was mostly happening for lldb_private::StackFrame objects
that had a member like "Thread &m_thread". So this completes the internal
strong/weak changes.
Documented the ExecutionContext and ExecutionContextRef classes so that our
LLDB developers can understand when and where to use ExecutionContext and
ExecutionContextRef objects.

The second part in thread hardening the internals of LLDB where we make
the lldb_private::StackFrame objects hold onto a weak pointer to the thread
object. The lldb_private::StackFrame objects the the most volatile objects
we have as when we are doing single stepping, frames can often get lost or
thrown away, only to be re-created as another object that still refers to the
same frame. We have another bug tracking that. But we need to be able to
have frames no longer be able to get the thread when they are not part of
a thread anymore, and this is the first step (this fix makes that possible
but doesn't implement it yet).
Also changed lldb_private::ExecutionContextScope to return shared pointers to
all objects in the execution context to further thread harden the internals.

Converted the lldb_private::Process over to use the intrusive
shared pointers.
Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.
Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size.
Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.

Convert lldb::ModuleSP to use an instrusive ref counted pointer.
We had some cases where getting the shared pointer for a module from

we can easily convert any pointer to a shared pointer.

Added "target variable" command that allows introspection of global
variables prior to running your binary. Zero filled sections now get
section data correctly filled with zeroes when Target::ReadMemory
reads from the object file section data.
Added new option groups and option values for file lists. I still need
to hook up all of the options to "target variable" to allow more complete
introspection by file and shlib.
Added the ability for ValueObjectVariable objects to be created with
only the target as the execution context. This allows them to be read
from the object files through Target::ReadMemory(...).
Added a "virtual Module * GetModule()" function to the ValueObject
class. By default it will look to the parent variable object and
return its module. The module is needed when we have global variables
that have file addresses (virtual addresses that are specific to
module object files) and in turn allows global variables to be displayed
prior to running.
Removed all of the unused proxy object support that bit rotted in
lldb_private::Value.
Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code
with the more efficient "FileSpec::Equal (lhs, rhs)".
Improved logging in GDB remote plug-in.

Process::ReadScalarIntegerFromMemory (lldb::addr_t addr, uint32_t byte_size, bool is_signed, Scalar &scalar, Error &error);
size_t
Process::WriteScalarToMemory (lldb::addr_t vm_addr, const Scalar &scalar, uint32_t size, Error &error);
in lldb_private::Process the following functions were renamed:
From:
uint64_t
Process::ReadUnsignedInteger (lldb::addr_t load_addr,
size_t byte_size,
Error &error);
To:
uint64_t
Process::ReadUnsignedIntegerFromMemory (lldb::addr_t load_addr,
size_t byte_size,
uint64_t fail_value,
Error &error);
Cleaned up a lot of code that was manually doing what the above functions do
to use the functions listed above.
Added the ability to get a scalar value as a buffer that can be written down
to a process (byte swapping the Scalar value if needed):
uint32_t
Scalar::GetAsMemoryData (void *dst,
uint32_t dst_len,
lldb::ByteOrder dst_byte_order,
Error &error) const;
The "dst_len" can be smaller that the size of the scalar and the least
significant bytes will be written. "dst_len" can also be larger and the
most significant bytes will be padded with zeroes.
Centralized the code that adds or removes address bits for callable and opcode
addresses into lldb_private::Target:
lldb::addr_t
Target::GetCallableLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;
lldb::addr_t
Target::GetOpcodeLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;
All necessary lldb_private::Address functions now use the target versions so
changes should only need to happen in one place if anything needs updating.
Fixed up a lot of places that were calling :
addr_t
Address::GetLoadAddress(Target*);
to call the Address::GetCallableLoadAddress() or Address::GetOpcodeLoadAddress()
as needed. There were many places in the breakpoint code where things could
go wrong for ARM if these weren't used.

Added functions to lldb_private::Address to set an address from a load address
and set the address as an opcode address or as a callable address. This is
needed in various places in the thread plans to make sure that addresses that
might be found in symbols or runtime might already have extra bits set (ARM/Thumb).
The new functions are:
bool
Address::SetCallableLoadAddress (lldb::addr_t load_addr, Target *target);
bool
Address::SetOpcodeLoadAddress (lldb::addr_t load_addr, Target *target);
SetCallableLoadAddress will initialize a section offset address if it can,
and if so it might possibly set some bits in the address to make the address
callable (bit zero might get set for ARM for Thumb functions).
SetOpcodeLoadAddress will initialize a section offset address using the
specified target and it will strip any special address bits if needed
depending on the target.
Fixed the ABIMacOSX_arm::GetArgumentValues() function to require arguments
1-4 to be in the needed registers (previously this would incorrectly fallback
to the stack) and return false if unable to get the register values. The
function was also modified to first look for the generic argument registers
and then fall back to finding the registers by name.
Fixed the objective trampoline handler to use the new Address::SetOpcodeLoadAddress
function when needed to avoid address mismatches when trying to complete
steps into objective C methods. Make similar fixes inside the
AppleThreadPlanStepThroughObjCTrampoline::ShouldStop() function.
Modified ProcessGDBRemote::BuildDynamicRegisterInfo(...) to be able to deal with
the new generic argument registers.
Modified RNBRemote::HandlePacket_qRegisterInfo() to handle the new generic
argument registers on the debugserver side.
Modified DNBArchMachARM::NumSupportedHardwareBreakpoints() to be able to
detect how many hardware breakpoint registers there are using a darwin sysctl.
Did the same for hardware watchpoints in
DNBArchMachARM::NumSupportedHardwareWatchpoints().

Added the ability to get the return value from a ThreadPlanCallFunction
thread plan. In order to get the return value, you can call:
void
ThreadPlanCallFunction::RequestReturnValue (lldb::ValueSP &return_value_sp);
This registers a shared pointer to a return value that will get filled in if
everything goes well. After the thread plan is run the return value will be
extracted for you.
Added an ifdef to be able to switch between the LLVM MCJIT and the standand JIT.
We currently have the standard JIT selected because we have some work to do to
get the MCJIT fuctioning properly.
Added the ability to call functions with 6 argument in the x86_64 ABI.
Added the ability for GDBRemoteCommunicationClient to detect if the allocate
and deallocate memory packets are supported and to not call allocate memory
("_M") or deallocate ("_m") if we find they aren't supported.
Modified the ProcessGDBRemote::DoAllocateMemory(...) and ProcessGDBRemote::DoDeallocateMemory(...)
to be able to deal with the allocate and deallocate memory packets not being
supported. If they are not supported, ProcessGDBRemote will switch to calling
"mmap" and "munmap" to allocate and deallocate memory instead using our
trivial function call support.
Modified the "void ProcessGDBRemote::DidLaunchOrAttach()" to correctly ignore
the qHostInfo triple information if any was specified in the target. Currently
if the target only specifies an architecture when creating the target:
(lldb) target create --arch i386 a.out
Then the vendor, os and environemnt will be adopted by the target.
If the target was created with any triple that specifies more than the arch:
(lldb) target create --arch i386-unknown-unknown a.out
Then the target will maintain its triple and not adopt any new values. This
can be used to help force bare board debugging where the dynamic loader for
static files will get used and users can then use "target modules load ..."
to set addressses for any files that are desired.
Added back some convenience functions to the lldb_private::RegisterContext class
for writing registers with unsigned values. Also made all RegisterContext
constructors explicit to make sure we know when an integer is being converted
to a RegisterValue.

Moved all code from ArchDefaultUnwindPlan and ArchVolatileRegs into their
respective ABI plugins as they were plug-ins that supplied ABI specfic info.
Also hookep up the UnwindAssemblyInstEmulation so that it can generate the
unwind plans for ARM.
Changed the way ABI plug-ins are handed out when you get an instance from
the plug-in manager. They used to return pointers that would be mananged
individually by each client that requested them, but now they are handed out
as shared pointers since there is no state in the ABI objects, they can be
shared.

Made lldb_private::ArchSpec contain much more than just an architecture. It
now, in addition to cpu type/subtype and architecture flavor, contains:
- byte order (big endian, little endian)
- address size in bytes
- llvm::Triple for true target triple support and for more powerful plug-in
selection.

Changing the ObjC find method implementation to use a ClangUtilityFunction inserted into the target. Consolidate all the
logic for finding the target of a method dispatch into this function, insert & call it. Gets calls to super, and all the
fixup & fixedup variants working properly. Also gets the class from the object so that we step through KVO wrapper methods
into the actual user code.

Modified the lldb_private::Type clang type resolving code to handle three
cases when getting the clang type:
- need only a forward declaration
- need a clang type that can be used for layout (members and args/return types)
- need a full clang type
This allows us to partially parse the clang types and be as lazy as possible.
The first case is when we just need to declare a type and we will complete it
later. The forward declaration happens only for class/union/structs and enums.
The layout type allows us to resolve the full clang type _except_ if we have
any modifiers on a pointer or reference (both R and L value). In this case
when we are adding members or function args or return types, we only need to
know how the type will be laid out and we can defer completing the pointee
type until we later need it. The last type means we need a full definition for
the clang type.
Did some renaming of some enumerations to get rid of the old "DC" prefix (which
stands for DebugCore which is no longer around).
Modified the clang namespace support to be almost ready to be fed to the
expression parser. I made a new ClangNamespaceDecl class that can carry around
the AST and the namespace decl so we can copy it into the expression AST. I
modified the symbol vendor and symbol file plug-ins to use this new class.

Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.
