[PATCH] D115996: [AMDGPU] Don't remove VGPR to AGPR dead spills from frame info

[Brendon Cahoon via Phabricator via llvm-commits]

bcahoon updated this revision to Diff 395937.
bcahoon added a comment.

Changes so that the VGPR to AGPR spill slot can be removed if stack slot coloring has not allocated multiple objects to the same slot. Added a couple extra test cases to check for different cases when the slot can/can't be removed.
