ZVBB64 was my intention: it has to be distinct from ZVBB or else `update_test_checks.py` reports a conflict. 

(Given that the output here in all cases except for RV64 is identical, I'm not sure what causes the conflict; I'd otherwise have assumed that two prefixes altogether, CHECK and RV64, suffice.)
