[PATCH] [Patch] Loop Interchange Pass

[Karthik Bhat]

Hi Hal,
Please find the updated patch attached. Addressed review comments and fixed few issues in Loop Interchange found during llvm lnt regression. After this change we find some improvement in execution time of 2 benchamrk test cases as shown in the previous post. There are few issues in Dependency analysis as you mentioned I'm planning to address it seperatly after looking into the module in more detail. Hope that should be fine?
Please let me know your inputs on the patch.
Thanks for your time and help.
Regards
Karthik Bhat
