[ARC] Update disassembler opcode selection
New instruction are added, and some of them are overlapping. Update
disassembler to correctly recognize them. Introduce nps400 option.
opcodes/
xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com>
* arc-dis.c (skip_this_opcode): Check also for 0x07 major opcodes,
and MPY class instructions.
(parse_option): Add nps400 option.
(print_arc_disassembler_options): Add nps400 info.
