[PATCH] D71435: [WIP] [Attributor] Function level undefined behavior attribute

[Stefanos Baziotis via Phabricator via llvm-commits]

baziotis updated this revision to Diff 234201.
baziotis added a comment.

- `manifest` that changes to uncreachable live UB loads.
- Set both for UB loads and non-UB loads.
- Stats that use UB loads.
- Method that checks if a specific (load) instruction is considered UB.

Note: Clang format did its job a little bit too well and replaced 2 parts that are not related to this patch. Should I remove them?
