[compiler-rt] [MemProf][compiler-rt] Add a test to ensure include files do not diverge (PR #97775)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/97775

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.

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.
