Folded in most of the changes highlighted in the review

There are also several new changes to the original patch in light of bugs
uncovered during further testing with applications using the support.

I haven't attempted to implement Matt's suggestion of using a struct return type
or 5-vec support. Could we add that as something to do at a later date?
Nicolai, do you have any feedback on that piece of work - my feeling is that it
is quite a complicated change based on how the intrinsics are defined. If not, I
can take another look if you can give some pointers.
