Fixed a problem where evaluating a breakpoint
condition in two different processes (with the
same target) could cause crashes. Now the breakpoint
condition is always evaluated (and possibly parsed)
by one thread at a time.

Optimized the way breakpoint conditions are evaluated.
Previously, the options for a breakopint or its
locations stored only the text of the breakpoint
condition (ironically, they used ClangUserExpression
as a glorified std::string) and, each time the condition
had to be evaluated in the StopInfo code, the expression
parser would be invoked via a static method to parse and
then execute the expression.
I made several changes here:
- Each breakpoint location now has its own
ClangUserExpressionSP containing a version of
the breakpoint expression compiled for that exact
location.
- Whenever the breakpoint is hit, the breakpoint
condition expression is simply re-run to determine
whether to stop.
- If the process changes (e.g., it's re-run) or
the source code of the expression changes (we use
a hash so as to avoid doing string comparisons)
the ClangUserExpressionSP is re-generated.
This should improve performance of breakpoint
conditions significantly, and takes advantage of
the recent expression re-use work.

After discussing with Chris Lattner, we require C++11, so lets get rid of the macros and just use C++11.

Since we use C++11, we should switch over to using std::unique_ptr when C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++.
Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro.

Cleanup - removing the ThreadPlanTestCondition and its helper functions. It is not needed,
since we now run the condition in the StopInfoBreakpoint's PerformAction, and don't need
to refer it to another "continue". Actually, we haven't needed to do this for a year or
so, I just hadn't gotten around to deleting the dead wood.

Switching back to using std::tr1::shared_ptr. We originally switched away
due to RTTI worries since llvm and clang don't use RTTI, but I was able to
switch back with no issues as far as I can tell. Once the RTTI issue wasn't
an issue, we were looking for a way to properly track weak pointers to objects
to solve some of the threading issues we have been running into which naturally
led us back to std::tr1::weak_ptr. We also wanted the ability to make a shared
pointer from just a pointer, which is also easily solved using the
std::tr1::enable_shared_from_this class.
The main reason for this move back is so we can start properly having weak
references to objects. Currently a lldb_private::Thread class has a refrence
to its parent lldb_private::Process. This doesn't work well when we now hand
out a SBThread object that contains a shared pointer to a lldb_private::Thread
as this SBThread can be held onto by external clients and if they end up
using one of these objects we can easily crash.
So the next task is to start adopting std::tr1::weak_ptr where ever it makes
sense which we can do with lldb_private::Debugger, lldb_private::Target,
lldb_private::Process, lldb_private::Thread, lldb_private::StackFrame, and
many more objects now that they are no longer using intrusive ref counted
pointer objects (you can't do std::tr1::weak_ptr functionality with intrusive
pointers).

Made GetConditionText const everywhere. Made it return NULL when there's no condition
like the doc's say it should. Make sure we have a condition before we set up a test whether
we have one, so we only present a "could not parse condition" error if we actually have a condition.

by being able to get the data count and data. Each thread stop reason
has one or more data words that can help describe the stop. To do this
I added:
size_t
SBThread::GetStopReasonDataCount();
uint64_t
SBThread::GetStopReasonDataAtIndex(uint32_t idx);

Added support for breakpoint conditions. I also had to separate the "run the expression" part of ClangFunction::Execute from the "Gather the expression result" so that in the case of the Breakpoint condition I can move the condition evaluation into the normal thread plan processing.
Also added support for remembering the "last set breakpoint" so that "break modify" will act on the last set breakpoint.

Abtracted the old "lldb_private::Thread::StopInfo" into an abtract class.
This will allow debugger plug-ins to make any instance of "lldb_private::StopInfo"
that can completely describe any stop reason. It also provides a framework for
doing intelligent things with the stop info at important times in the lifetime
of the inferior.
Examples include the signal stop info in StopInfoUnixSignal. It will check with
the process to see that the current action is for the signal. These actions
include wether to stop for the signal, wether the notify that the signal was
hit, and wether to pass the signal along to the inferior process. The
StopInfoUnixSignal class overrides the "ShouldStop()" method of StopInfo and
this allows the stop info to determine if it should stop at the signal or
continue the process.
StopInfo subclasses must override the following functions:
virtual lldb::StopReason
GetStopReason () const = 0;
virtual const char *
GetDescription () = 0;
StopInfo subclasses can override the following functions:
// If the subclass returns "false", the inferior will resume. The default
// version of this function returns "true" which means the default stop
// info will stop the process. The breakpoint subclass will check if
// the breakpoint wants us to stop by calling any installed callback on
// the breakpoint, and also checking if the breakpoint is for the current
// thread. Signals will check if they should stop based off of the
// UnixSignal settings in the process.
virtual bool
ShouldStop (Event *event_ptr);
// Sublasses can state if they want to notify the debugger when "ShouldStop"
// returns false. This would be handy for breakpoints where you want to
// log information and continue and is also used by the signal stop info
// to notify that a signal was received (after it checks with the process
// signal settings).
virtual bool
ShouldNotify (Event *event_ptr)
{
return false;
}
// Allow subclasses to do something intelligent right before we resume.
// The signal class will figure out if the signal should be propagated
// to the inferior process and pass that along to the debugger plug-ins.
virtual void
WillResume (lldb::StateType resume_state)
{
// By default, don't do anything
}
The support the Mach exceptions was moved into the lldb/source/Plugins/Process/Utility
folder and now doesn't polute the lldb_private::Thread class with platform
specific code.

Add a "thread specification" class that specifies thread specific breakpoints by name, index, queue or TID.
Push this through all the breakpoint management code. Allow this to be set when the breakpoint is created.
Fix the Process classes so that a breakpoint hit that is not for a particular thread is not reported as a
breakpoint hit event for that thread.
Added a "breakpoint configure" command to allow you to reset any of the thread
specific options (or the ignore count.)
