> We need to handle the case when the allocation input to `VectorBoxNode` is a phi but the vector input is not, which can definitely be the case if the vector input has been value-numbered. It seems to be safe to do by construction because `VectorBoxNode` and `VectorBoxAllocation` come in a specific order as a result of expanding an intrinsic call. After that, if any of the inputs to VectorBoxNode are value-numbered they can only move up and are guaranteed to dominate.
