    [cleanup] Do not emit temp registers for instructions that don't need them · cab91c71
    Ng Zhi An authored
    A lot of the instructions in RO_OP_LIST do not require temp registers in
    the codegen, but a temp register is emitted. We split RO_OP_LIST into
    two lists, one which requires temp registers RO_OP_LIST_ONE_TEMP, and
    RO_OP_LIST is now for instructions that do not use temp registers.
    
    There are a couple more instructions currently in RO_OP_LIST, but use
    scratch registers in the codegen, those can be cleaned up to use temp
    registers and then moved into RO_OP_LIST_ONE_TEMP.
