This patch attempts to update the ISA specification according
to the latest mailing list discussion about conformance groups,
in a way that is intended to be consistent with IANA registry
processes and IETF 118 WG meeting discussion.
It does the following:
* Split basic into base32 and base64 for 32-bit vs 64-bit base
instructions
* Split division/multiplication/modulo instructions out of base groups
* Split atomic instructions out of base groups
There may be additional changes as discussion continues,
but there seems to be consensus on the principles above.
v1->v2: fixed typo pointed out by David Vernet
v2->v3: Moved multiplication to same groups as division/modulo
