*   Add TensorSpec to represent the specification of Tensors.
    *   Constant folding pass is now deterministic.
    *   Support `float16` `dtype` in `tf.linalg.*`.
    *   Add `tf.estimator.export.TensorServingInputReceiver` that allows
        `tf.estimator.Estimator.export_savedmodel` to pass raw tensors to model
        functions.
