* mips.h: Document new field descriptors +Q.
(OP_SH_SEQI, OP_MASK_SEQI): New bit mask and shift count for SEQI.
opcodes/
* mips-dis.c (print_insn_args): Handle field descriptor +Q.
* mips-opc.c (mips_builtin_opcodes): Add Octeon instructions seq,
seqi, sne and snei.
gas/
* config/tc-mips.c (validate_mips_insn): Handle field descriptor +Q.
(mips_ip): Likewise.
(macro_build): Likewise.
(CPU_HAS_SEQ): New macro.
(macro2) <M_SEQ_I, M_SNE_I>: Use it. Emit seq/sne and seqi/snei.
gas/testsuite/
* gas/mips/octeon.s, gas/mips/octeon.d: Add tests for seq* and sne*.
* gas/mips/octeon-ill.s, gas/mips/octeon-ill.s: Add tests for seqi
and snei.
