Is there actually any reason to believe compiler could do this in near future? Personally, I can point to huge amount of easy to predict branches in my code, but pretty much everything else I have no idea. So it's hard for me to see how a compiler could know, but maybe there's something I'm missing.

There's PGO of course, but that really only works for interpreted or jitted languages.
