Move Spliterator.shouldNotSplit to ParallelPipelineHelper.suggestSplit
ensuring that Spliterator is only about splitting and element access.
ParallelPipelineHelper is in a better position to centralize the
suggestion that a split should be peformed given information on spliterator
and properties both static and dynamic of the F/J pool and platform.
