[llvm] r303375 - LLVM_FALLTHROUGH instead of fall-through comment.

[Rui Ueyama via llvm-commits]

You need to include llvm/Support/Compiler.h to use LLVM_FALLTHROUGH, but
doing that is probably not preferred because the file is written in a way
that reduces dependency to LLVM.

Since this broke the build, I'm going to revert.
