[PATCH] D75741: AMDGPU: Add check to recompute merge-able instructions

[David Stuttard via Phabricator via llvm-commits]

dstuttard added a comment.

I encountered this issue with a test shader I was looking at. I did manage to create a reproducer, but a different fix to the triviallyDisjoint function meant that it stopped happening.
However, I still think the situation may occur, hence putting this change up for review.

If the consensus is that it is valid, I can try to create a test case for it.
