GCC 4.8 provides a nice solution, which takes care of build and dispatch.

Main issue is that the function can't get inlined.

> Currently, compiling with SSE3 is the default option, but we may wish to utilize optimizations that require SSE 4.x. Also, it should be possible to disable SSE / SIMD entirely (not sure if anyone would want to compile all this to run on a Raspberry Pi but you never know).
