[PATCH] D48102: Improve handling of COPY instructions with identical value numbers

[Tim Renouf via Phabricator via llvm-commits]

tpr added a comment.

With this, I'm getting a different assert "CopyMI input register not live" in one test case. I'll narrow it down and check I can reproduce it on upstream LLVM with your fix (as opposed to our local branch with your fix).
