    openmp: c++: Consider typeinfo decls to be predetermined shared [PR91118]

    If the typeinfo decls appear in OpenMP default(none) regions, as we no
longer
    predetermine const with no mutable members, they are diagnosed as errors,
    but it isn't something the users can actually provide explicit sharing for
in
    the clauses.
