Implement generic upsample()
Reduces all vector upsamples down to its scalar components, so probably
not the most efficient thing in the world, but it does what the
spec says it needs to do.
Another possible implementation would be to convert/cast everything as
unsigned if necessary, upsample the input vectors, create the upsampled
value, and then cast back to signed if required.
