[PATCH] D71799: [Attributor] AAUndefinedBehavior: Check for branches on undef value.

[Stefanos Baziotis via Phabricator via llvm-commits]

baziotis updated this revision to Diff 235310.
baziotis added a comment.

- Clarification on the uses of the 2 sets.

I was trying to get `AAValueSimplify` to work on the memory accessing instructions as well but at some point along the way
I ran the whole Attributor suite. **Important**: Unfortunately, it seems that this patch breaks 3 other test cases. Specifically, the `changeToUnreachable` part. I couldn't
understand why, I'll come back tomorrow. Please feel free to propose ideas (it seems that `AAIsDead` has problems with it).
