This is like `Save` except that tensors can be listed in the saved file as being
a slice of a larger tensor.  `shapes_and_slices` specifies the shape of the
larger tensor and the slice that this tensor covers. `shapes_and_slices` must
have as many elements as `tensor_names`.

Elements of the `shapes_and_slices` input must either be:

*  The empty string, in which case the corresponding tensor is
   saved normally.
