Cycles Refactor: Add SSE Utility code from Embree for cleaner SSE code. This makes the code a bit easier to understand, and might come in handy if we want to reuse more Embree code. Differential Revision: https://developer.blender.org/D482 Code by Brecht, with fixes by Lockal, Sergey and myself.

Cycles: Slight modification to the previous commit This way util_simd.cpp would not require modifications if/when SSE2 is suddenly supported on 32bit platforms. This also allowed to unleash some issues with util_simd.h related on the fact that there size_t and int are actually the same types.
