The problem with this approach is that I believe it conflicts with the goal of moving more tests from debugloc.ll into this new file. We'll get to the point where we need so many `--filter` options to catch all the various `dbg` annotations that we may as well just to generate all of the CHECK lines. That's why I chose to manually add the CHECK lines for the ones I care about. If you still prefer to use the `filter` argument I'm happy to do so, but there will be plenty of them.
