[PATCH] D29996: [DeadStoreElimination] Check function modref behavior before considering memory clobbered

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added a comment.

So
A. This added test still fails with this patch for me :)
B. I see this is only used in the case where the code is trying to eliminate redundant stores, so seems okay otherwise.
