Dalai Felinto	8d3cc431d7	Fix T41471 Cycles Bake: Setting small tile size results in wrong bake with stripes rather than the expected noise pattern This problem was introduced in 983cbafd1877f8dbaae60b064a14e27b5b640f18 Basically the issue is that we were not getting a unique index in the baking routine for the RNG (random number generator).

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.
