[PATCH] D64393: [AMDGPU] Fix DPP combiner check for exec modification

[Valery Pykhtin via Phabricator via llvm-commits]

vpykhtin added a comment.

I missed r363675 commit and I think the original semantics of isEXECMaskConstantBetweenDefAndUses should be restored: there should be no scan after the last use.

execMayBeModifiedBeforeUse should be called as it was originally to check all uses at once to prevent rollback.
