do-mirp
If "round" is "yes," we just go with the cut-in value. The cut-in
actually determines how we set bit 3, because having the cut-in
off implies that rounding MUST be off, while the round state can
be anything (including "no") if the cut-in is "yes."
If "round" is anything but "yes," we explicitly set the round state,
calling the template that changes round state (but we do not store).
Then, at the end, we call the template that restores the stored
round state (it will be the previous one). Thus the round state that
is specified for this instruction applies only to this instruction.
If "ref-pt" is specified, we set RP0 before we do the MIRP or MDRP.
