[PATCH] D41953: [LoopUnroll] Unroll and Jam

Hi Dave,

With respect to the awkward ordering, I don't understand why this transformation (as a standalone pass) couldn't perform the inner unrolling itself? I don't see why there needs to be a dependency. Also, will have loop rotate as a utility (https://reviews.llvm.org/D44595) help simplify this transform?

cheers,
sam
