[PATCH] D127942: [NewGVN] add context instruction for SimplifyQuery

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

SimplifyContext is created with `CxtI=nullptr` though, so I would expect it to not use a context instruction. Is the problem here that InstSimplify calls into ValueTracking helps like isKnownNonZero, and those convert CxtI==nullptr into the passed instruction in safeCxtI?
