        (nacro): Use them.  Remove *_OB and *_DOB cases.  For single-
        register load and store macros, handle the 16-bit offset case first.
        If a 16-bit offset is not suitable for the instruction we're
        generating, load it into the temporary register using
        ADDRESS_ADDI_INSN.  Make the M_LI_DD code fall through into the
        M_L_DAB code once the address has been constructed.  For double load
        and store macros, again handle the 16-bit offset case first.
        If the second register cannot be accessed from the same high
        part as the first, load it into AT using ADDRESS_ADDI_INSN.
        Fix the handling of LD in cases where the first register is the
        same as the base.  Also handle the case where the offset is
        not 16 bits and the second register cannot be accessed from the
        same high part as the first.  For unaligned loads and stores,
        fuse the offbits == 12 and old "ab" handling.  Apply this handling
        whenever the second offset needs a different high part from the first.
        Construct the offset using ADDRESS_ADDI_INSN where possible,
        for offbits == 16 as well as offbits == 12.  Use offset_reloc
        when constructing the individual loads and stores.
        (mips_ip): Set up imm_expr, imm2_expr, offset_expr, imm_reloc
        and offset_reloc before matching against a particular opcode.
        Handle elided 'A' constants.  Allow 'A' constants to use
        relocation operators.
