[PATCH] D111846: [LV] Drop NUW/NSW flags from instructions that need predication

[Diego Caballero via Phabricator via llvm-commits]

dcaballe updated this revision to Diff 381129.
dcaballe added a comment.

Addressed the feedback:

- Replaced 'clearUnsafeFlagsAfterLinearizingCF' with 'Instruction::dropPoisonGeneratingFlags'
- Added logic to drop 'inbounds' from a VPGepWidenRecipe
- Addressed all the tests impacted by the new changes (quite a few)

Please, let me know if anything else is missing.
Thanks!
