The checks in this test are generated by using update_test_checkes.py, and then I remove some redundant debug metadata checks and keep the `DBG29`. So, if someone regenerate the checks, the crucial checks would still be there.

For those instruction checks, I think we can only keep those of `.exit.thread4`.
