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 839ed1b 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.
