Daily Pathtracer part 8, where I'm learning more SIMD, and add more spheres to the test scene.

@aras Really enjoying the series - I started on a SIMD version of my own last night. One thing that I'm trying is replacing the 3 mults + 2 adds when computing dot products with 2 fmadd + 1 mult instructions. I haven't compared speed yet though - it might pipeline worse, cancelling out any advantage.
