[PATCH] D51742: [AMDGPU] Fix regression with not maintaining MachineDominatorTree

[Scott Linder via Phabricator via llvm-commits]

scott.linder added a comment.

The regression was caught by the expensive_checks build, if that is sufficient for testing? I am actually not sure how to write a lit test for this, because `opt -analyze` will just re-calculate the DT; I don't know how to just print the DT after the legalize pass runs.
