Hans Wennborg 1667136f5e Option parsing: properly handle flag aliases for joined options (PR23394)
A joined option always needs to have an argument, even if it's an empty one.

Clang would previously assert when trying to use --extra-warnings, which is
a flag alias for -W, which is a joined option.
