//// (1) if the shift amount belongs to the "B" operand, (bypass) and since we only shift right
//// when B is a denorm (it has a bit on) then the maximum shift right is (52) because
//// the smallest b exponent (expo min) after prenorm is -52.
//// there is the possibility that a divide could create an artificially small Bexpo.
//// if that is true the shift right amount should be zero (right 64 followed by left 0).
//// (2) otherwise the right shift amount comes from the product exponent.
//// the product exponent could be very small, however for a multiply add if it becomes
//// too small then the exponent will come from the addend, so no problem.
//// a multiply instruction does not have an addend, and it could have a very small exponent.
//// BUT, the lead bit is at [55] and even if the shift right goes right 64 followed by left 64,
//// it will not but a bit into the result or guard fields.
