[PATCH] D117796: AMDGPU: Fix LiveVariables error after lowering SI_END_CF

[Ruiling, Song via Phabricator via llvm-commits]

ruiling added a comment.

I would hope we can move the block split logic into a separate pass that can be scheduled before we constructing liveness information, like during addPreRegAlloc(). It is expensive to update either LiveVariables or LiveIntervals. Sounds good?
