Also, __builtin_shufflevector allows to say -1 as a don't care element, our
current infrastructure doesn't allow that, but it would be nice even for
internal uses. On the other side, I think __builtin_shufflevector allows only
constant indices, while __builtin_shuffle allows arbitrary runtime reshuffling.
