[Andrey Turetskiy via llvm-commits]

aturetsk added a comment.

1. Rebased to the newer trunk.
2. The loop rotation pass has been ported to the new pass manager. Extend this patch for the new version of the pass as well.
3. Use approach #3 (with bool variable keeping information about the createLoopRotatePass argument).
