in parallel under distribution strategy.
    *   Speed up `GradientTape` in eager mode by auto-generating list of op
        inputs/outputs which are unused and hence not cached for gradient
        functions.
    *   Support `back_prop=False` in `while_v2` but mark it as deprecated.
    *   Improve error message when attempting to use `None` in data-dependent
        control flow.
