wow. in combination with swizzle, twin-predication, elwidth overrides, and
saturation i had no idea until i looked at it how stupidly powerful and
flexible this instruction is.

the only thing i just realised is, damn, it really does need to be joined by a
two-in and two-out variant.

the reason is that you may have some left audio in one vector and right in
another.  they need zipping up.  likewise for pixels.
