* mips-opc.c (WR_1, WR_2, RD_1, RD_2, RD_3, RD_4, MOD_1, MOD_2, UDI):
New macros.

(WR_z, WR_Z, RD_z, RD_Z, RD_d): Delete.
(mips_builtin_opcodes): Use the new position-based read-write flags
instead of field-based ones. Use UDI for "udi..." instructions.
* mips16-opc.c (WR_1, WR_2, RD_1, RD_2, RD_3, RD_4, MOD_1, MOD_2):
New macros.
(WR_x, WR_y, WR_z, WR_Y, RD_x, RD_y, RD_Z, RD_X): Delete.
(RD_T, WR_T, WR_31): Redefine using generic INSN_* flags.
(WR_SP, RD_16): New macros.
(RD_SP): Redefine as an INSN2_* flag.
(MOD_SP): Redefine in terms of RD_SP and WR_SP.
(mips16_opcodes): Use the new position-based read-write flags
instead of field-based ones. Use RD_16 for "nop". Move RD_SP to
pinfo2 field.
* micromips-opc.c (WR_1, WR_2, RD_1, RD_2, RD_3, RD_4, MOD_1, MOD_2):
New macros.

(WR_T, WR_S, RD_s, RD_b, RD_t, RD_T, RD_S, RD_R, RD_D): Delete.
(RD_sp, WR_sp): Redefine to INSN2_READ_SP and INSN2_WRITE_SP.
(micromips_opcodes): Use the new position-based read-write flags
instead of field-based ones.
* mips-dis.c (print_insn_arg): Use mips_decode_reg_operand.
(print_insn_mips, print_insn_micromips): Use INSN_WRITE_1 instead
of field-based flags.

* config/tc-mips.c (MAX_OPERANDS): New macro.
(mips_operand_array): New structure.
(mips_operands, mips16_operands, micromips_operands): New arrays.
(micromips_to_32_reg_b_map, micromips_to_32_reg_c_map)
(micromips_to_32_reg_e_map, micromips_to_32_reg_f_map)

(micromips_to_32_reg_q_map): Delete.
(insn_operands, insn_opno, insn_extract_operand): New functions.
(validate_mips_insn): Take a mips_operand_array as argument and
use it to build up a list of operands. Extend to handle INSN_MACRO
and MIPS16.
(validate_mips16_insn): New function.
(validate_micromips_insn): Take a mips_operand_array as argument.
Handle INSN_MACRO.
(md_begin): Initialize mips_operands, mips16_operands and
micromips_operands. Call validate_mips_insn and
validate_micromips_insn for macro instructions too.
Call validate_mips16_insn for MIPS16 instructions.
(insn_read_mask, insn_write_mask, operand_reg_mask, insn_reg_mask):
New functions.
(gpr_read_mask, gpr_write_mask, fpr_read_mask, fpr_write_mask): Use
them. Handle INSN_UDI.
