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.
