An Op to permute tensors across replicated TPU instances.
tf.raw_ops.CollectivePermute( input, source_target_pairs, name=None ) Each instance supplies its own input.
For example, suppose there are 4 TPU instances: [A, B, C, D]. Passing source_target_pairs=[[0,1],[1,2],[2,3],[3,0]] gets the outputs: [D, A, B, C].
