[PATCH] D105344: [DAGCombiner] Fold SETCC(FREEZE(x), y) to SETCC(x, y) if used by BRCOND

[Juneyoung Lee via Phabricator via llvm-commits]

aqjune added a comment.

This optimization seems still helpful after D105392 <https://reviews.llvm.org/D105392> is landed.
Should we generalize this transform and optimize away all freezes used by BRCOND? This will need an introduction of a new helper function that is analogous to `canCreateUndefOrPoison`.
