Summary: This patch reimplements heuristic that tries to estimate optimization beneftis from complete loop unrolling. In this patch I kept the minimal changes - e.g. I removed code handling branches and folding compares. That's a promising area, but now there are too many questions to discuss before we can enable it. Test Plan: Tests are included in the patch.
