[PGO] Add runtime hook so that IR instrumentation can override version IR level instrumentation needs to override version with variant bits. No change for FE instrumentation is needed. Test case is added to detect version mismatch. llvm-svn: 257230

// RUN: %clang_profgen -o %t -O3 %s
[profile] PROF_ERR, PROF_WARN 1) Move common prefix to the macro def 2) Introduced PROF_WARN 3) Make error message unconditionally printed out. llvm-svn: 270185
