[PATCH] D94746: [AMDGPU] Move kill lowering to WQM pass and add live mask tracking

[Carl Ritson via Phabricator via llvm-commits]

critson updated this revision to Diff 317205.
critson added a comment.

Remove VCC def flags from SI_KILL_I1 and add test.
This bug existed prior to this patch, but was not causing any issues as control flow lowering does not track liveness.
However it matters for WQM lowering of kills as it can lead to stray definitions of VCC.
