Subject: [PATCH] * mips.h (OP_SH_MT_U, OP_MASK_MT_U, OP_SH_MT_H, OP_MASK_MT_H,
 OP_SH_MTACC_T, OP_MASK_MTACC_T, OP_SH_MTACC_D, OP_MASK_MTACC_D): New define.
 Document !, $, *, &, g, +t, +T operand formats for MT instructions.
 (INSN_ASE_MASK): Update to include INSN_MT. (INSN_MT): New define for MT ASE.
