[Bf-cycles] BVH8

[Móra Péter]

Hi,

Is there any point adding AVX2 support to BVH8? Or Blender/Cycles will
use Embree now, and that's working fine?

[I'm new to Blender, but I have some time, I know the basics of AVX2,
started to read BVH code both in Cycles and Embree, I'm a
Mathematician, etc.]

Thanks,
 Peter
