Thomas Dinges 866c7fb6e6 Cycles: Add an AVX2 CPU kernel.
This kernel is compiled with AVX2, FMA3, and BMI compiler flags. At the moment only Intel Haswell benefits from this, but future AMD CPUs will have these instructions as well.

Makes rendering on Haswell CPUs a few percent faster, only benchmarked with clang on OS X though.

Part of my GSoC 2014.
