d6efd25d - functionalization: check for undefined tensors in advanced indexing (#90791)

functionalization: check for undefined tensors in advanced indexing (#90791) It looks like running code like `a[:, tensor_idx] = b` can results in: (1) calling `index_put_()` (2) passing (potential undefined) tensors as the indices to index_put_().
