[PATCH] D88328: [InferAttrs] Improve DSE for libcalls (partial fix for PR47644)

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added a comment.

Ok, I should be ready to make progress here again.

@fhahn, with manually added writeonly, this optimization no longer works for me somehow.

Any recent change in MSSA DSE which could cause this behaviour?
