[PATCH] [LoopInterchange] Add support to interchange loops with reductions.

[Karthik Bhat]

Hi Renato,
Updated code as per reveiw comments. Refactored reduction identification code out of loop vectorizer and reusing the same in this pass. This code assumes http://reviews.llvm.org/D9046 has been applied.

Please let me know your inputs on this.

Thanks for your continued support. I really appreciate it.

Thanks and Regards
Karthik Bhat
