SIMD support...

And generally, if the D compiler receives just D vector ops, what's a good way for the compiler to map them efficiently (even if less efficiently than true SIMD operations written manually) to SIMD ops? Generally you can't ask all D programmers to use __float4, some of them will want to use just D vector ops, despite they are a less efficient, because they are simpler to use. So the duty of a good D compiler is to implement them too efficiently enough.
