Reland (Attempt #3) PR #35985: [TFLite int16] 16-bit version of ADD/SUB reference kernel operators

Imported from GitHub PR https://github.com/tensorflow/tensorflow/pull/35985

This PR is one of steps to extend 8-bit quantization to support symmetric 16-bit activations.

Each activation is of type int16 and symmetric around zero. The weight tensor precision remains at 8-bit signed values. The bias is set to int64 precision.

In this PR we introduce implementation and tests for ADD/SUB kernel reference function.
The specification of this operator:

SUB
  Input 0:
    data_type  : int16
    range      : [-32768, 32767]
    granularity: per-tensor, zero_point=0
  Input 1:
    data_type  : int16
    range      : [-32768, 32767]
    granularity: per-tensor, zero_point=0
  Output 0:
    data_type  : int16
    range      : [-32768, 32767]
    granularity: per-tensor, zero_point=0

ADD
  Input 0:
    data_type  : int16
    range      : [-32768, 32767]
    granularity: per-tensor, zero_point=0
  Input 1:
    data_type  : int16
    range      : [-32768, 32767]
    granularity: per-tensor, zero_point=0
  Output 0:
    data_type  : int16
    range      : [-32768, 32767]
    granularity: per-tensor, zero_point=0

Documentation

TensorFlow is an end-to-end open source platform for machine learning. It has a comprehensive, flexible ecosystem of tools, libraries, and community resources that lets researchers push the state-of-the-art in ML and developers easily build and deploy ML-powered applications.

TensorFlow was originally developed by researchers and engineers working on the Google Brain team within Google's Machine Intelligence Research organization to conduct machine learning and deep neural networks research. The system is general enough to be applicable in a wide variety of other domains, as well.

TensorFlow provides stable Python and C++ APIs, as well as non-guaranteed backward compatible API for other languages.

Keep up-to-date with release announcements and security updates by subscribing to announce@tensorflow.org. See all the mailing lists.

Install

See the TensorFlow install guide for the pip package, to enable GPU support, use a Docker container, and build from source.

To install the current release, which includes support for CUDA-enabled GPU cards (Ubuntu and Windows):

$ pip install tensorflow

A smaller CPU-only package is also available:

$ pip install tensorflow-cpu

To update TensorFlow to the latest version, add --upgrade flag to the above commands.

Nightly binaries are available for testing using the tf-nightly and tf-nightly-cpu packages on PyPi.

Try your first TensorFlow program

$ python

>>> import tensorflow as tf
>>> tf.add(1, 2).numpy()
3
>>> hello = tf.constant('Hello, TensorFlow!')
>>> hello.numpy()
b'Hello, TensorFlow!'

For more examples, see the TensorFlow tutorials.
