  Log Message:
  -----------
  llvm-reduce: Don't print verifier failed machine functions (#109673)

This produces far too much terminal output, particularly for the
instruction reduction. Since it doesn't consider the liveness of of
the instructions it's deleting, it produces quite a lot of verifier
errors.
