[PATCH] D90640: [LoopFlatten] Widen the IV

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

> now using RecursivelyDeleteDeadPHINode at the end to clean up dead phis. Doing this earlier proved to be a bit tricky with a few things in flight, but at least a nice clean up at the end.

----------------
dso_local and local_unnamed_addr #0 can be removed.
