[PATCH] D15157: CodeGen peephole: fold redundant phys reg copies

[JF Bastien via llvm-commits]

jfb added a comment.

This now passes all tests with `ninja check` on a build with all backends, and seems to do what I want! I'll clean up the code a bit, test it on Chrome some more (including the issue I posted above).
