Adds the movbi, decode1, fbset, fbclear, encode0, encode1, rflt, crc16,
and crc32 instructions for the nps400 arc machine type.

gas/ChangeLog:

	* testsuite/gas/arc/nps400-1.d: Update expected results.
	* testsuite/gas/arc/nps400-1.s: Additional test cases.

opcodes/ChangeLog:

	* arc-nps400-tbl.h: Add movbi, decode1, fbset, fbclear, encode0,
	encode1, rflt, crc16, and crc32 instructions.
	* arc-opc.c (arc_flag_operands): Add F_NPS_R.
	(arc_flag_classes): Add C_NPS_R.
	(insert_nps_bitop_size_2b): New function.
	(extract_nps_bitop_size_2b): Likewise.
	(insert_nps_bitop_uimm8): Likewise.
