Convert the following Integer Multiply-Accumulate opcodes:
* MACC Multiply, accumulate, and move LO
* MACCHI Multiply, accumulate, and move HI
* MACCHIU Unsigned multiply, accumulate, and move HI
* MACCU Unsigned multiply, accumulate, and move LO
Since all opcodes are generated using the same pattern, we
add the gen_helper_mult_acc_t typedef and MULT_ACC() macro
to remove boilerplate code.
