These had been templated on a type, and then the width of that type was
considered the amount the PC should advance when executing straight line
code. That type was MachInst, which was loosely the size of an
instruction, but was practically whatever sized data type was fed into
the decoder at a time.
Instead of tying this to a type, this change moves it over to be a
simple number. This avoids a level of indirection, and also further
decouples the type the decoder might use as input from the instruction
size.
