Cycles: Implementation of object reference nodes spatial split
This commit implements object reference node spatial split making it possible
to use spatial split for top-level BVH.
The code is not in use yet because enabling spatial split on top level BVH is
not coming for free and it needs to be investigated if it's worth in terms of
improved render times.
