            * trans.h (struct lang_type, struct lang_decl): Remove span member.
            (GFC_DECL_SPAN, GFC_TYPE_ARRAY_SPAN): Remove macros.
            * trans-array.h (gfc_get_descriptor_offsets_for_info): Add another
            argument.
            * trans-array.c (gfc_get_descriptor_offsets_for_info): Add SPAN_OFF
            argument and initialize *SPAN_OFF to the offset of span field.
            * trans-types.c (gfc_get_array_descr_info): Adjust
            gfc_get_descriptor_offsets_for_info caller.  Compute elem_size
            as base->span instead of TYPE_SIZE_UNIT (etype) constant.
