You cannot call REGNO on something that isn't a REG, and you cannot

The way I fixed nios2_alternate_compare_const is admittedly a bit lame.

        * config/nios2/nios2.c (nios2_simple_const_p): Returns false if the
        argument isn't a CONST_INT.
        (nios2_alternate_compare_const): Set *alt_code and *alt_op to code
        and op if op is not a CONST_INT.
        (nios2_valid_compare_const_p): Return false if the argument isn't
        a CONST_INT.
        (ldstwm_operation_p): Return false if first_base is not a REG or
        if first_offset is not a CONST_INT.

OK.
