Brainstorming: Noise optimization

[worktycho]

I'll have a go at this over the weekend. I want to learn sse and avx so it'l be useful for me even if turns out ten times slower. I'll write a benchmark as well as it would be useful to see how the speeds compare. Not sure how to write an interface that depending on compile settings can return an array or an array of ints, may have to resort to macros.
