There is no direct AVX instruction to convert to unsigned. I have some ideas how we may be able to do this with three vector instructions but the current backend just bails on this to get it scalarized. See the comment why we need to adjust the cost returned by BasicTTI. The test is a bit roundabout (and checks assembly rather than bit code) because I'd like it to work even if at some point we could vectorize this conversion.
