Log:
    PR fortran/50981
    * trans-array.h (gfc_walk_elemental_function_args): New argument.
    * trans-intrinsic.c (gfc_walk_intrinsic_function): Update call.
    * trans-stmt.c (gfc_trans_call): Ditto.
    * trans-array.c (gfc_walk_function_expr): Ditto.
    (gfc_walk_elemental_function_args): Get the dummy argument list
    if possible.  Check that the dummy and the actual argument are both
    optional, and set can_be_null_ref accordingly.
