Ping ~ There is no functional change by this patch, but just cleanup of those unnecessary use of output modifiers. All these instruction sequences are always with fixed format, we can just hardcode the relocation modifiers into instruction patterns, then all those redundant checks in aarch64_print_operand can be removed.
