This was causing a test failure in omp_test_if.c when building with GCC in

[CMake] Providing a CMake cache for 3-stage builds
This cache file can be used to generate a 3-stage clang build. You can configure using the following CMake command:
cmake -C <path to clang>/cmake/caches/3-stage.cmake -G Ninja <path to llvm>
You can then run "ninja stage3-clang" to build stage1, stage2 and stage3 clangs.
This is useful for finding non-determinism the compiler by verifying that stage2 and stage3 are identical.

Fix an issue where pressing CTRL+C in the interactive script interpreter causes LLDB to crash
This is because PyThreadState_Get() assumes a non-NULL thread state and crashes otherwise; but PyThreadState_GET is just a shortcut (in non-Python-debugging builds) for the global variable that holds the thread state
The behavior of CTRL+C is slightly more erratic than one would like. CTRL+C in the middle of execution of Python code will cause that execution to be interrupted (e.g. time.sleep(1000)), but a CTRL+C at the prompt will just cause a KeyboardInterrupt and not exit the interpreter - worse, it will only trigger the exception once one presses ENTER.
None of this is optimal, of course, but I don't have a lot of time to appease the Python deities with the proper spells right now, and fixing the crasher is already a good thing in and of itself

Refactor PGO function naming and MD5 hashing support out of ProfileData
Summary:
Move the function renaming logic into the Function class, and the
MD5Hash routine into the MD5 header.
This will enable these routines to be shared with ThinLTO, which
will be changed to store the MD5 hash instead of full function name
in the combined index for significant size reductions. And using the same
function naming for locals in the function index facilitates future
integration with indirect call value profiles.

`addUsedIfAvailable<T>` in `getAnalysisUsage` to indicate to the
