opcodes/arc: Add yet more nps instructions

Add some more arc/nps400 instructions and the associated operands.
There's also a test added into the assembler.

gas/ChangeLog:

	* testsuite/gas/arc/nps400-6.d: New file.
	* testsuite/gas/arc/nps400-6.s: New file.

include/ChangeLog:

	* opcode/arc.h (MAX_INSN_ARGS): Increase 6 to 8.

opcodes/ChangeLog:

	* arc-nps400-tbl.h: Add addb, subb, adcb, sbcb, andb, xorb, orb,
	fxorb, wxorb, shlb, shrb, notb, cntbb, div, mod, divm, and qcmp
	instructions.
	* arc-opc.c (insert_nps_bitop_size): Delete.
	(extract_nps_bitop_size): Delete.
	(MAKE_SRC_POS_INSERT_EXTRACT_FUNCS): Define, and use.
	(extract_nps_qcmp_m3): Define.
	(extract_nps_qcmp_m2): Define.
	(extract_nps_qcmp_m1): Define.
	(arc_flag_operands): Add F_NPS_SX, F_NPS_AR, F_NPS_AL.
	(arc_flag_classes): Add C_NPS_SX, C_NPS_AR_AL
	(arc_operands): Add NPS_SRC2_POS, NPS_SRC1_POS, NPS_ADDB_SIZE,
	NPS_ANDB_SIZE, NPS_FXORB_SIZ, NPS_WXORB_SIZ, NPS_R_XLDST,
	NPS_DIV_UIMM4, NPS_QCMP_SIZE, NPS_QCMP_M1, NPS_QCMP_M2, and
