@nikic and @dtcxzyw thanks for the feedback.

This patch does bypasses the need for freeze poison -> null canonicalization removal in InstCombine. To provide context I am seeing the lack of store of select freeze poison folding in uninitialized memory semantics work that I am doing with @nlopes.

I would like to incorporate this and then once freeze poison -> null canonicalization is removed from InstCombine refactor appropriately. Would this be acceptable?
