    *   Allow sparse float splits to support multivalent feature columns.
    *   Add `quantile` to `tf.distributions.TransformedDistribution`.
    *   Add `NCHW_VECT_C` support for `tf.depth_to_space` on GPU.
    *   Add `NCHW_VECT_C` support for `tf.space_to_depth` on GPU.

## API Changes

*   Rename `SqueezeDims` attribute to `Axis` in C++ API for Squeeze op.
*   `Stream::BlockHostUntilDone` now returns Status rather than bool.
