Begin implementing ARC NPS-400 Accelerator instructions

opcodes * arc-nps400-tbl.h: Change block comments to GNU format.
        * arc-dis.c: Add new globals addrtypenames,
        addrtypenames_max, and addtypeunknown.
        (get_addrtype): New function.
        (print_insn_arc): Print colons and address types when
        required.
        * arc-opc.c: Add MAKE_INSERT_NPS_ADDRTYPE macro and use to
        define insert and extract functions for all address types.
        (arc_operands): Add operands for colon and all address
        types.
        * arc-nps-400-tbl.h: Add NPS-400 BMU instructions to opcode table.
        * arc-opc.c: Add NPS_BD_TYPE and NPS_BMU_NUM operands,
        insert_nps_bd_num_buff and extract_nps_bd_num_buff functions.
        * arc-nps-400-tbl.h: Add NPS-400 PMU instructions to opcode table.
        * arc-opc.c: Add NPS_PMU_NXT_DST and NPS_PMU_NUM_JOB operands,
        insert_nps_pmu_num_job and extract_nps_pmu_num_job functions.

include * opcode/arc.h: Add ARC_OPERAND_ADDRTYPE,
        ARC_OPERAND_COLON. Add the arc_nps_address_type enum and
        ARC_NUM_ADDRTYPES.
        * opcode/arc.h: Add BMU to insn_class_t enum.
        * opcode/arc.h: Add PMU to insn_class_t enum.

gas     * config/tc-arc.c: Add new global arc_addrtype_hash.
        Define O_colon and O_addrtype.
        (debug_exp): Add O_colon and O_addrtype.
        (tokenize_arguments): Handle colon and address type
        tokens.
        (declare_addrtype): New function.
        (md_begin): Initialise arc_addrtype_hash.
        (arc_parse_name): Add lookup of address types.
	(assemble_insn): Handle colons and address types by
        ignoring them.
        * testsuite/gas/arc/nps400-8.s: New file.
        * testsuite/gas/arc/nps400-8.d: New file.
        * testsuite/gas/arc/nps400-8.s: Add PMU instruction tests.
        * testsuite/gas/arc/nps400-8.d: Add expected PMU
        instruction output.
