Name matching was working inconsistently across many places in LLDB. Anyone doing name lookups where you want to look for all types of names should used "eFunctionNameTypeAuto" as the sole name type mask. This will ensure that we get consistent "lookup function by name" results. We had many function calls using as mask like "eFunctionNameTypeBase | eFunctionNameTypeFull | eFunctionNameTypeMethod | eFunctionNameTypeSelector". This was due to the function lookup by name evolving over time, but as it stands today, use eFunctionNameTypeAuto when you want general name lookups. Either ModuleList::FindFunctions() or Module::FindFunctions() will figure out the right kinds of names to lookup and remove the "eFunctionNameTypeAuto" and replace it with the exact subset of what the name can be.
This checkin also changes eFunctionNameTypeAny over to use eFunctionNameTypeAuto to reflect this.

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.

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.

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.

Extended function lookup to allow the user to
indicate whether inline functions are desired.
This allows the expression parser, for instance,
to filter out inlined functions when looking for
functions it can call.

Changed the SymbolFile::FindFunction() function calls to only return
lldb_private::Function objects. Previously the SymbolFileSymtab subclass
would return lldb_private::Symbol objects when it was asked to find functions.
The Module::FindFunctions (...) now take a boolean "bool include_symbols" so
that the module can track down functions and symbols, yet functions are found
by the SymbolFile plug-ins (through the SymbolVendor class), and symbols are
gotten through the ObjectFile plug-ins.
Fixed and issue where the DWARF parser might run into incomplete class member
function defintions which would make clang mad when we tried to make certain
member functions with invalid number of parameters (such as an operator=
operator that had no parameters). Now we just avoid and don't complete these
incomplete functions.

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.

Added function name types to allow us to set breakpoints by name more
intelligently. The four name types we currently have are:
eFunctionNameTypeFull = (1 << 1), // The function name.
// For C this is the same as just the name of the function
// For C++ this is the demangled version of the mangled name.
// For ObjC this is the full function signature with the + or
// - and the square brackets and the class and selector
eFunctionNameTypeBase = (1 << 2), // The function name only, no namespaces or arguments and no class
// methods or selectors will be searched.
eFunctionNameTypeMethod = (1 << 3), // Find function by method name (C++) with no namespace or arguments
eFunctionNameTypeSelector = (1 << 4) // Find function by selector name (ObjC) names
this allows much more flexibility when setting breakoints:
(lldb) breakpoint set --name main --basename
(lldb) breakpoint set --name main --fullname
(lldb) breakpoint set --name main --method
(lldb) breakpoint set --name main --selector
The default:
(lldb) breakpoint set --name main
will inspect the name "main" and look for any parens, or if the name starts
with "-[" or "+[" and if any are found then a full name search will happen.
Else a basename search will be the default.
Fixed some command option structures so not all options are required when they
shouldn't be.
Cleaned up the breakpoint output summary.
Made the "image lookup --address <addr>" output much more verbose so it shows
all the important symbol context results. Added a GetDescription method to
many of the SymbolContext objects for the more verbose output.
