[PATCH] D99149: [LoopUnrollAndJam] Change LoopUnrollAndJamPass to LoopNest pass

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

This sounds good to me, so long as all the existing tests are still doing OK.

Does it work, in general, to have a loop pass that creates and destroys loops? Even if the outer loop is completely unrolled?

And does unroll and jam preserve memory-ssa correctly?
