This seems fine, but one alternative I figured I'd mention would be to
maintain a map of used streams in the wined3d_stream_info structure,
analogous to the existing "use_map" we have for used elements/input
attributes, and then using wined3d_bitmap_get_range() or
wined3d_bit_scan() to iterate over them.
