[llvm-commits] if-conversion using mbpi

[Jakub Staszak]

Hello,

This patch changes If-Conversion algorithm so it uses MachineBranchProbabilityInfo instead of its own heuristics. I (Andy) run SPEC tests on ARM machine and it looks that in a few cases we get 4-5% boost, without any bigger regressions. I had to change a few test however so they don't fail on "make check". Can you look at them at make sure it is fine?

Thanks!
- Kuba
