[Progress]BVH with SSE

Finally I finish my BVH with SSE implementation, but the outcome for a simple model (66454 triangles) doesn't seem like helpful.

Here is the outcome:

Without SSE

==BVH Info==

1-element leaf: 1838

2-element leaf: 18209

3-element leaf: 2876

4-element leaf: 2811

Total: 27047 bounding boxes

Building time: 2.453573 sec

==Rendering Info==

Rendering time: 1.565233 sec

Ray-Box intersection: 19658128

Ray-Triangle intersection: 1393575

With SSE

==BVH Info==

1-element leaf: 0

2-element leaf: 1

3-element leaf: 0

4-element leaf: 16613

Total: 16614 bounding boxes

Building time: 2.569810 sec

==Rendering Info==

Rendering time: 1.429016 sec

Ray-Box intersection: 19821888

Ray-Triangle intersection: 673405

Two weeks for 0.1 sec improvement. Cool!!
