[PATCH] D18158: Adding ability to unroll loops using epilogue remainder.

[Evgeny Stupachenko via llvm-commits]

evstupac updated this revision to Diff 52183.
evstupac added a comment.

Tried to minimize UseEpilogRemainder condition blocks.
The change affect tests (which I have not updated yet). If you agree the change is better solution, I'll update tests.
