Well, perhaps this check ought to be done as a standalone test rather
than as debug build validation. I don't really have any deep commitment
either way. However, if we do proceed with this I think it ought to be
in a separate follow-up patch and with its own JIRA. It should not stop
Ningsheng's SVE patch going in as is since that merely corrects the
status quo to allow for SVE instructions.
