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.
