[PATCH] D27114: Preserve nonnull metadata on Loads through SROA & mem2reg.

[Luqman Aden via Phabricator via llvm-commits]

luqmana updated this revision to Diff 92597.
luqmana added a comment.

I added another test for all the relevant codepaths in PromoteMemoryToRegister.
I also addressed one case I missed earlier: when the alloca in question has
multiple stores but all within the same basic block.
