* `crternlogi` is similar to the group of CR Operations (crand, cror etc) which have
been identified as a Binary Lookup Group, except an 8-bit
immediate is used instead of a 4-bit one, and up to 4 bits of a CR Field may
- be computed at once, saving 3 CR operations.
+ be computed at once, saving at least 3 groups of CR operations.
* `crbinlut` is similar to the Binary Lookup Group of CR Operations except that the
4-bit lookup table comes from a CR Field instead of from an Immediate. Also
like `crternlogi` up to 4 bits may be computed at once.
