Is this true - it looks like there are additional checks you've added by hand (at least the `DBG29` check)?

If someone came along and regenerated the checks using update_test_checks.py I'm worried we'd lose the ones you added (I'm not super familiar with  update_test_checks.py - maybe you could check this out?).

As an aside, I'm not sure we need to check each instruction here either, just enough to be sure the transformation has happened - possibly it would be enough to just check the `.exit.thread4:` block contents?
