   Advance a thread-block parallel BVH query and return the next batch of results as a tile.
   
   Every thread in the block must call this on each loop iteration. Guard the traversal
   loop with :func:`~warp.tile_query_valid` and test each returned index for ``>= 0``.
   
   :param query: The query to advance, from :func:`~warp.tile_bvh_query_aabb` or
                 :func:`~warp.tile_bvh_query_ray`
   
   :returns: A register tile of shape ``(block_dim,)`` and dtype ``int`` holding one result
             index per thread: the index of an overlapping bound into the ``lowers``/``uppers``
             arrays passed to :class:`warp.Bvh`, or a negative value when that thread has no
             result.
   
   See :func:`~warp.tile_bvh_query_aabb` for a usage example.
