The idea is that we copy the test, run the check and apply fixes, then run the
check again to make sure there are no more warnings. (I’m not sure how much
value this adds on top of the usual `CHECK-FIXES`. I wouldn’t be against
removing it too.) Making a separate file would cause duplication: we would need
to check in both the original and the fixed file, right?
