Subject: Add RXv3 instructions.

        * rx-decode.opc (DSIZE): New. double size.
        (_ld): New. dmov size attribute.
        (PSCALE): Add double size.
        (DCR, DDR, DDRH, DDRL, DCND): New. Double FPU registers.
        (SCR, SDR, SDRH, SDRL): Likewise.
        (S2DR, S2CR): Likewise.
        (SDD): New. double displacement.
        (DL): New. Set dmov size attribute.
        (rx_decode_opcode): Add RXv3 instructions.
        * rx-decode.c: Regenerate.
        * rx-dis.c (size_names): Add double entry.
        (opsize_names): Likewise.
        (double_register_names): New. Double FPU registers.
        (double_register_high_names): Likewise.
        (double_register_low_names): Likewise.
        (double_register_control_names): Likewise.
        (double_condition_names): dcmp condition.
        (print_insn_rx): Add  bfmov / bfmovz output.
        Add double FPU output.
