Subject: [PATCH 1/2] [MemProf][compiler-rt] Add a test to ensure include files
 do not diverge

Memprof has two include files that are duplicated between LLVM and
compiler-rt. They need to stay in sync to ensure correct functionality,
but the comments can be somewhat easy to miss, which causes fixups like
839ed1ba553346b0c225e9b839cf3cb716dc7412 to be needed. This patch adds a
test to ensure that the files are the same between LLVM and compiler-rt
to catch this ideally before commit, but if not, soon afterwards.
