[PATCH] D22630: Loop rotation

[Sebastian Pop via llvm-commits]

sebpop added a comment.

Looks almost good to me.
Aditya, let's also post your changes that address the comment from @eli.friedman on the idempotence of loop rotation.
The changes are an adaptation of the annotation technique used in the loop vectorizer to avoid vectorizing twice the same loop.
Thanks!
