Compilers like MWCC 2.3 fairly commonly, and since they are kinda simple I thought it would be good to have them

paddub: Behaves like addu but for quad registers. From what I have seen it is mostly used as a move
sq/lq: Those behave like sw and lw but for quad registers. Most commonly used to save registers into the stack
