* mips.h: Remove "mi" documentation. Update "mh" documentation.
(OP_MASK_MI, OP_SH_MI, MICROMIPSOP_MASK_MI, MICROMIPSOP_MASK_MI):
Delete.
(INSN2_WRITE_GPR_MHI): Rename to...
(INSN2_WRITE_GPR_MH): ...this.
opcodes/
* micromips-opc.c (WR_mhi): Rename to..
(WR_mh): ...this.
(micromips_opcodes): Update "movep" entry accordingly. Replace
"mh,mi" with "mh".
* mips-dis.c (micromips_to_32_reg_h_map): Rename to...
(micromips_to_32_reg_h_map1): ...this.
(micromips_to_32_reg_i_map): Rename to...
(micromips_to_32_reg_h_map2): ...this.
(print_micromips_insn): Remove "mi" case. Print both registers
in the pair for "mh".
gas/
* config/tc-mips.c (mips32_to_micromips_reg_h_map): Delete.
(micromips_to_32_reg_h_map): Rename to...
(micromips_to_32_reg_h_map1): ...this.
(micromips_to_32_reg_i_map): Rename to...
(micromips_to_32_reg_h_map2): ...this.
(mips_lookup_reg_pair): New function.
(gpr_write_mask, macro): Adjust after above renaming.
(validate_micromips_insn): Remove "mi" handling.
(mips_ip): Likewise. Parse both registers in a pair for "mh".
