Its also worth noting that SSE5 is (yet another) weird naming scheme in
the superset scheme of things. AMD has announced it, but its not a
superset of (all) of SSE4 but a competitor for (some) of it.
Just to muddy the water a little more.
I imagine when SSE5 is finalized and shipped we'll add support for it to
Mono.Simd as well.
