* mips.h: Document new field descriptors +x, +X, +p, +P, +s, +S.
        Update comment before MIPS16 field descriptors to mention MIPS16.
        (OP_SH_BBITIND, OP_MASK_BBITIND): New bit mask and shift count for
        BBIT.
        (OP_SH_CINSPOS, OP_MASK_CINSPOS, OP_SH_CINSLM1, OP_MASK_CINSLM1):
        New bit masks and shift counts for cins and exts.

gas/

        * config/tc-mips.c (validate_mips_insn): Handle field descriptors
        +x, +X, +p, +P, +s, +S.
        (mips_ip): Likewise.

opcodes/

        * mips-dis.c (print_insn_args): Handle field descriptors +x, +p,
        +s, +S.
        * mips-opc.c (mips_builtin_opcodes): Add Octeon instructions
        baddu, bbit*, cins*, dmul, pop, dpop, exts*, mtm*, mtp*, syncs,
        syncw, syncws, vm3mulu, vm0 and vmulu.

gas/testsuite/

        * gas/mips/octeon.s, gas/mips/octeon.d: Add tests for baddu,
        bbit*, cins*, dmul, pop, dpop, exts*, mtm*, mtp*, syncs, syncw,
        syncws, vm3mulu, vm0 and vmulu.
        * gas/mips/octeon-ill.s, gas/mips/octeon-ill.s: New test.
        * gas/mips/mips.exp: Run it.  Run octeon test with
        run_dump_test_arches.

Octeon:
"+x" Bit index field of bbit. Enforces: 0 <= index < 32.
"+X" Bit index field of bbit aliasing bbit32. Matches if 32 <= index < 64,
otherwise skips to next candidate.
"+p" Position field of cins/cins32/exts/exts32. Enforces 0 <= pos < 32.
"+P" Position field of cins/exts aliasing cins32/exts32. Matches if
32 <= pos < 64, otherwise skips to next candidate.
"+s" Length-minus-one field of cins/exts. Enforces: 0 <= lenm1 < 32.
"+S" Length-minus-one field of cins32/exts32 or cins/exts aliasing
cint32/exts32. Enforces non-negative value and that
pos + lenm1 < 32 or pos + lenm1 < 64 depending whether previous
position field is "+p" or "+P".
