[PATCH] D20078: PGO] Fix __llvm_profile_raw_version linkage in MACHO

Wow, so without this fix are IR profiles unusable on macho? I'm not sure if I'm understanding this correctly because it doesn't seem like that could pass testing.

Also, is "weak_def_can_be_hidden" incorrect because __llvm_profile_raw_version isn't supposed to be "hidden"? I'd appreciate it if you could point me to any resources that discuss the difference between weak_def_can_be_hidden and weak_definition -- if there aren't any I can dig a bit more :).
