        * mips.igen (PREFX): Tweak instruction opcode fields (i.e.,
        add a comma) so that it more closely match the MIPS ISA
        documentation opcode partitioning.
        (PREF): Put useful names on opcode fields, and include
        instruction-printing string.

        * mips.igen (check_u64): New function which in the future will
        check whether 64-bit instructions are usable and signal an
        exception if not.  Currently a no-op.
