- LABEL is important to give a better diagnostic in case a check pattern fails
- Some NOT negative patterns are not effective. NEXT is useful to ensure a code sequence has the desired instructions and report a better diagnostic if something goes off.
- Since the ABI says the first parameter is in RDI. Replacing the pattern `[[REG16:.*]]` with `RDI` should not cause maintenance burden.

Since the test is pretty mechanical, just use update_llc_test_checks.py
to re-generate it. Most functions can use `nounwind` to avoid CFI
directives.
