    *   `partial_tensor_shape.h` -> `../framework/partial_tensor_shape.h`
    *   `tensorflow_server.h` deleted
*   For C++ API users: `TensorShape::ShortDebugString` has been renamed to
    `DebugString`, and the previous `DebugString` behavior is gone (it was
    needlessly verbose and produced a confusing empty string for scalars).
*   `GraphOptions.skip_common_subexpression_elimination` has been removed. All
