Cycles: Store time in BVH nodes

This way we can stop traversing BVH node early on.

Gives about 2-2.5x times render time improvement with 3 BVH steps.
Hopefully this gives no measurable performance loss for scenes with
single BVH step.

Traversal is currently only implemented for QBVH, meaning old CPUs
and GPU do not benefit from this change.
