[PATCH] D97427: [AMDGPU] Do not annotate an else branch if there is a kill

[Carl Ritson via Phabricator via llvm-commits]

critson added a comment.

With respect to the searching that this adds, I ran this on 14069 graphics pipelines from them this invoked the search 13735 times.
Mean 5.5 instructions were visited during the search and the worst case was 33 instructions.
So I think the cost of doing this is low.

I am still in two minds about whether to do this or stop lowering kills to block terminators, but this is the smaller change.
