[PATCH] D76890: [GlobalISel] Fix equality for copies from physregs in matchEqualDefs

[Jessica Paquette via Phabricator via llvm-commits]

paquette added a comment.

The existing test had

  %a:_(s32) = COPY $w0
  %b:_(s32) = COPY $w0

which is no longer folded

but yeah it would probably be better to be clear in the testcase about why this isn't folded, so I'll change it.
