LGTM. My comments can be addressed in a separate patch.

I think we should have a way to express that the values are case insensitive, instead of enumerating all possible combinations.

   HelpText<"Which overload candidates to show when overload resolution fails: "
-           "best|all; defaults to all">;

 def fshow_column : Flag<["-"], "fshow-column">, Group<f_Group>, Flags<[CC1Option]>;
We should be able to express which value is the default value if nothing is specified. A non-very readable solution would be to put the default always as the first value.
