[PATCH] D107180: [InstCombine] Prevent unnecessary sinks caused by the Freeze

[Juneyoung Lee via Phabricator via llvm-commits]

aqjune added a comment.

As suggested, finding a common dominator and sinking the instruction to the location seems reasonable and worth trying.
It will help reduce the diff at line 3866~, I hope.
If `DT` is null, fallback to the old one use check?
