We don't want to autocomplete flags whose Flags class has `NoDriverOption` when argv[1] is not `-cc1`.

Another idea for this implementation is to make --autocomplete a cc1
option and handle it in clang Frontend, by porting --autocomplete
handler from Driver to Frontend, so that we can handle Driver options
and CC1 options in unified manner.
