[PATCH] D80120: [InstCombine] Sink pure instructions down to return and unreachable blocks

[Alina Sbirlea via Phabricator via llvm-commits]

asbirlea added a comment.

FWIW, the added tests look good.

I don't really see how the case of not sinking from A when A and B blocks merge in C can happen, if this applies for non-memory instructions only. But if it can, having a test for this would be good too.
