[PATCH] D101546: [AMDGPU] Fix v_swap_b32 formation on physical registers

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

We don't need to rely on kill flags (and in fact should not, since they are semi-deprecated). We should be using liveness scans starting from the bottom of the block which do not need kill flags
