This fix reduces the stack size of SymbolFileDWARF::ParseType(). It seems that clang is not very good at sharing locations on the stack with local variables in large functions that have many blocks and each variable gets unique locations. The reduction in size was done by:
1 - removing some large locals that were default constructed by not used
2 - Placing some larger local variables into std::unique_ptr<> to make them on the heap
3 - removing local variables there were large and being populated but not being used
4 - reducing the size of some typedefs to llvm::SmallVector<T, N> so that N wasn’t excessively large

This is a purely mechanical change explicitly casting any parameters for printf
style conversion. This cleans up the warnings emitted by gcc 4.8 on Linux.

This is a mechanical change addressing the various sign comparison warnings that
are identified by both clang and gcc. This helps cleanup some of the warning
spew that occurs during builds.

You can either provide the function name, or function body text.
Also propagate the compilation error up from where it is checked so we can report compilation errors.

On FreeBSD ptrace(PT_KILL) is used to terminate the traced process
(as if PT_CONTINUE had been used with SIGKILL as the signal to be
delivered), and is the desired behaviour for ProcessPOSIX::DoDestroy.
On Linux, after ptrace(PTRACE_KILL) the traced process still exists
and can be interrogated. It is only upon resume that it exits as though
it received SIGKILL.
As the Linux PTRACE_KILL behaviour is not used by LLDB, rename
BringProcessIntoLimbo to Kill, and change the implementation to simply
call kill() instead of using ptrace.
Thanks to Todd F for testing (Ubuntu 12.04, gcc 4.8.2).

Store the gpr data in a DataBufferHeap and use a DataExtractor to
extract register values with appropriate endianness. This avoids hard-
coding the register count, and with some further work would allow this
class to provide generic register context storage for any CPU.

For now I'm committing only the FreeBSD change, until the Linux change
(review D3159) is successfully tested.

For some reason, the libc++ vector<bool> data formatter was essentially a costly no-up, doing everything required of it, except actually generating the child values!
This restores its functionality

Since dosep.ty started invoking multiple tests in parallel, the FreeBSD
buildbot occasionally has a failure due to os.mkdir returning EEXIST.
Silently ignore that exception, but reraise any other.

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.
It builds cleanly against TOT llvm with xcodebuild. I updated the
cmake files by visual inspection but did not try a build. I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.
In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

condition where we could end up killing debugserver (and thus the target) before it had a chance
to detach.
Also fix debugserver to send the OK AFTER it detaches to avoid the same race condition.

For small structs, the frame format now prints them as one-liners
This follows the same definition that frame variable does for deciding what a "small struct" is, and as such should be fairly consistent with the variable display in general
