[PATCH] D152082: [ValueTracking] getUnderlyingObject() look through phi.

[Joshua Cao via Phabricator via llvm-commits]

caojoshua added a comment.

I tried reducing the compile time in https://github.com/caojoshua/llvm-project/tree/underlyingperf. From local results, I'm able to eliminate regressions in the NFC by moving away from std::function. Regressions are still very significant for the functionality changing patch.
