[PATCH] D15503: [PGO] Shorten profile symbol prefixes

[Vedant Kumar via llvm-commits]

This is a good idea. There are quite a few tests in llvm and clang which need updating. The clang changes can come later, but I'd expect `s/llvm_profile_/prf_/g`-style changes to llvm/test along with this patch.
