[AMDGPU] Fix read-undef flags when schedule is reverted If two subregs of the same register are defined and we need to revert schedule changing def order, we will end up with both instructions having def,read-undef flags because adjustLaneLiveness() will only set this flag but will not remove it. Fix this by removing read-undef flags before calling adjustLaneLiveness. Differential Revision: https://reviews.llvm.org/D30428 llvm-svn: 296484
