Rong Xu 33c76c0cc2 [PGO] Differentiate Clang instrumentation and IR level instrumentation profiles ... This patch uses one bit in profile version to differentiate Clang instrumentation and IR level instrumentation profiles. PGOInstrumenation generates a COMDAT variable __llvm_profile_raw_version so that the compiler runtime can set the right profile kind. For Maco-O platform, we generate the variable as linkonce_odr linkage as COMDAT is not supported. PGOInstrumenation now checks this bit to make sure it's an IR level instrumentation profile. The patch was submitted as r260164 but reverted due to a Darwin test breakage.
