Paul Koning 223f080724 PDP10, PDP11, VAX: Make DMC/DMR initialization more accurate. ...

These changes cure a number of issues in RSTS/E, which is more
sensitive to details of emulation than most:

1. Additional KMC opcodes supported for ROMI
2. MCLR now initializes the CSRs per the spec
3. MCLR and ROMI are processed immediately at CSR write rather than
   being deferred, because these actions are implemented in the device
   hardware rather than in the microprogram.
