    Fortran/OpenMP: Fix privatization of associated names

    gfc_omp_predetermined_sharing cases the associate-name pointer variable
    to be OMP_CLAUSE_DEFAULT_FIRSTPRIVATE, which is fine. However, the
associated
    selector is shared. Thus, the target of associate-name pointer should not
get
    copied. (It was before but because of gfc_omp_privatize_by_reference
returning
    false, the selector was not only wrongly copied but this was also not done
    properly.)

    gcc/fortran/ChangeLog:

            PR fortran/103039
            * trans-openmp.cc (gfc_omp_clause_copy_ctor, gfc_omp_clause_dtor):
            Only privatize pointer for associate names.

    libgomp/ChangeLog:

            PR fortran/103039
            * testsuite/libgomp.fortran/associate4.f90: New test.
