Connor Wakamo 93fcbed8b6 [frontend] Switch from a default case to OPT_UNKNOWN for catching unknown arguments.
The integrated frontend already doesn't handle certain arguments which it understands (such as, for the moment, '-c'), so only emit an error in the event of an unknown option, not just unhandled options.
