Ok.  Here is why I responded to this in the first place.

I'm about to code up VIS primitive support for the Sparc backend and
it's likely to not use the vector stuff gcc has at all.  It simply
doesn't fit very well with VIS.

So this, along with your comments, makes it seem to me that we
should just mark these simd test cases as expecting to pass only
on the platforms where there is explicit vector support right now.
