        * trans-array.c (gfc_conv_scalarized_array_ref): Do not fix
        info->descriptor but pass it directly to gfc_build_array_ref.
        (gfc_conv_array_ref): Likewise for se->expr.
        * trans.c (gfc_build_array_ref): If 'decl' is a COMPONENT_REF
        obtain the span field directly from it.
