Broadcast an array to a compatible shape NumPy-style.
The tensor's shape is compared to the broadcast shape from end to beginning.
Ones are prepended to the tensor's shape until it has the same length as
the broadcast shape. If input.shape[i]==shape[i], the (i+1)-th axis is
already broadcast-compatible. If input.shape[i]==1 and shape[i]==N, then
the input tensor is tiled N times along that axis (using tf.tile).
