Corrects 16-bit read-modify-write.
Subject to the TODO proviso on 'correct'; has my 6502 prejudice pushed me into unrealistic bus signalling?

Ties to 8- or 16-bit those instructions that aren't M/X-dependent.
This is technically redundant for PEI, PEA and PER since they have dedicated bus programs anyway, but it's good to be explicit.
