    Adjust 'gfortran.dg/goacc/privatization-1-*' [PR103576, PR103697]

    ... for the recent commit 494ebfa7c9aacaeb6ec1fccc47a0e49f31eb2bb8
    "Fortran: Handle compare in OpenMP atomic", which changes the GIMPLE IR
    such that a temporary is no longer used; 'original' dump:

                 x =3D *a;
        -        {
        -          integer(kind=3D4) D.4237;
        -
        -          D.4237 =3D *a;
                   #pragma omp atomic relaxed
        -            &y =3D D.4237;
        -        }
        +          &y =3D *a;
               }

    (I'm not familiar to comment whether that's correct; but it appears that
the
    difference again disappears in later compiler passes.)

    These OpenACC test cases verify behavior re OpenACC privatization level=
s,
and
    have to be adjusted accordingly.
