Some HBO optimizations do not apply to Prestissimo because native workers do not produce necessary stats.

For example, RandomizeNullKeyInOuterJoin optimization relies on nullJoinBuildKeyCount and joinBuildKeyCount stats in join's build side.

It would be nice to document all HBO optimizations and clarify what stats are needed to enable these, so that these can be added to Prestissimo.
