opcodes/arc: Implement style support in the disassembler
Update the ARC disassembler to supply style information to the disassembler output. The output formatting remains unchanged. opcodes/ChangeLog: * disassemble.c (disassemble_init_for_target): Set created_styled_output for ARC based targets. * arc-dis.c (find_format_from_table): Use fprintf_styled_ftype instead of fprintf_ftype throughout. (find_format): Likewise. (print_flags): Likewise. (print_insn_arc): Likewise. Signed-off-by: Claudiu Zissulescu <claziss@gmail.com>
