Cleaner approach: I extracted the relevant MIR and added to existing test file `fix-sgpr-copies.mir`, which runs the `si-fix-sgpr-copies` that executes the code in `SIInstrInfo.cpp`. I re-generated file checks for all tests in the file since they were originally generated with an earlier version of the file check utility. No changes to the `RUN` line.
