On second thoughts, and having investigate things a bit further ...
Doing it would revert any architecture [still] defining REGISTER_BYTE
(almost all of them) back to using the legacy register cache.
Consequently I'll instead just add sanity checks to ensure that the
regcache and REGISTER_BYTE are consistent.

Appears to work.
> Sounds like it's time to s/ REGISTER_BYTE / DEPRECATED_REGISTER_BYTE /. It isn't yet possible to eliminate that macro from the MIPS since it is that hardwired mystery that defines the MIPS remote protocol :-(
