Cycles: Calculate face normal on the fly.

Browse Source 
Instead of pre-calculation and storage, we now calculate the face normal during render.
This gives a small slowdown (~1%) but decreases memory usage, which is especially important for GPUs,
where you have limited VRAM.

Part of my GSoC 2014.
