Alyssa Rosenzweig 01fcca884b OpcodeDispatcher: Optimize rotates
In the non-immediate cases, we can amortize some work between the two
flags to come out 1 instruction ahead.

In the immediate case, costs us an extra 2 instructions compared to
before we packed NZCV flags, but this mitigates a bigger instr count
regression that this PR would otherwise have. Coming out ahead will
require FlagM and smarter RA, but is doable.
