        * resolve.c (find_array_spec): If this is a class expression
        and the symbol and component array specs are the same, this is
        not an error.
        *trans-intrinsic.c (gfc_conv_intrinsic_size): If a class symbol
        argument, has no namespace, it has come from the interface
        mapping and the _data component must be accessed directly.
        * trans-array.c (gfc_trans_create_temp_array): Compute elemsize
        in all cases and use to set span field.
        (gfc_is_reallocatable_lhs): Pick up class allocatable exprs
        that do not have a _data component ref before the array ref.
