Mark Emmer b63b3953d2 SDS: Allow display or entry of NOP with optional operands ...

While debugging DDT subsystem of 940 time-sharing system, discovered NOP opcode used with indirection, non-zero operand address and tag field. I_V_OPO (opcode only) was redundant with I_V_NPN (no operand) opcode classes. Convert I_V_OPO to new "operand optional" class and use it for NOP, and add code to detect presence or absence of operand or tag for this class for machine code display and entry.
