    c: _Generic should not warn in non-active branches
[PR68193,PR97100,PR110703]

    To avoid false diagnostics, use c_inhibit_evaluation_warnings when
    a generic association is known to not match during parsing.  We may
    still generate false positives if the default branch comes earler than
    a specific association that matches.
