[llvm-dev] questionabout loop rotation

[Aditya K via llvm-dev]

hi,
I had an implementation of loop-rotation that peels the loop such that each conditional is executed at least once.
https://reviews.llvm.org/D22630

This helps with LICM when instructions inside a conditional is loop invariant. The patch has decent number of test cases.
All the requested comments were addressed at that time. I'm happy to rebase and put the patch again.
