simd comparison operator?

[Manu]

I don't think opCmp can fit that model?

But aside from that, I think that's misleading, and suggests to the user
that it's a trivial operation.
Additionally, it's not necessarily even possible in a portable way.

I also think most users would expect that comparison operators produce a
boolean result.
They'll be surprised when: if(a > b) produces an error.
