[PATCH] D43245: [LoopInterchange] Support reductions across inner and outer loop.

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Updated based on https://reviews.llvm.org/D53027, to keep sets PHIs that are part of inner loop only and  across the inner and outer loop. This makes the checks during transform trivial. It also ensures that we do not deal with unclassified PHIs.
