[PATCH] D83926: [ValueTracking] Let isGuaranteedNotToBeUndefOrPoison use Operator, look into more ops

[Juneyoung Lee via Phabricator via llvm-commits]

aqjune added a comment.

For this, `canCreatePoison` seems to be helpful. I'll add a patch that

- refactors `canCreatePoison` so it takes an operator
- add a function `canCreateUndef`

and make this patch call invoke the two functions.
