As mentioned in D93793, there are quite a few places where unary `IRBuilder::CreateShuffleVector(X, Mask)` can be used instead of `IRBuilder::CreateShuffleVector(X, Undef, Mask)`. Let's update them. Actually, it would have been more natural if the patches were made in this order: (1) let them use unary CreateShuffleVector first (2) update IRBuilder::CreateShuffleVector to use poison as a placeholder value (D93793) The order is swapped, but in terms of correctness it is still fine.
