    Fortran/OpenMP: Fix declare_variant's 'adjust_args' mishandling with return
by reference [PR118321]

    declare_variant's 'adjust_args' clause references the arguments in the
    middle end by the argument position; this has to account for hidden
    arguments that are inserted before due to return by reference,
    as done in this commit.

            * trans-openmp.cc (gfc_trans_omp_declare_variant): Honor hidden
            arguments for append_arg's need_device_ptr.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/gomp/adjust-args-12.f90: New test.
