  Add functionality to fold batch norm (supporting both fused and unfused batch norm) to support quantized training. The weights are always now scaled by gamma/sigma, where sigma is the moving standard deviation for stability prior to quantization.  For improved performance, the moving means and variances are frozen and the training graph modified accordingly.
  Add iterate_batches arg to Estimator.predict
  Make jit_test.py work with C API enabled.
  [XLA] add DotGeneral to the local Python XLA client.
  Revert TensorBoard entry point back to run_main
  Internal change.
  Throw an exception when the user's batch size isn't divisible by GPUs.
