Thanks @xbolva00 for your comment.

//"This is disabled by default for non-PGO builds, right?"//
Yes, it is disabled for non-pgo by default.

//Did you try to benchmark the patch for non PGO mode? There are various heuristic already in LLVM which are enabled for non-PGO mode too if they generally improve the perf.//
Yes, I did. For non-pgo mode, there are no significant improvements and one noticeable degradation for benchmark  povray (4.7% degradation)
