[PATCH] D63044: [LangRef] Clarify poison semantics

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

Also LGTM.  Nice cleanup.

I will separately raise a conversation of whether storing poison should be immediate UB, but I'm explicitly OK w/it being removed in this patch given nothing actually appears to implement that semantic at the moment.
