> Predicate Pull up on Project can also pull up deterministic functions whose
> arguments are all literals.
> Ex: select r1.x from (select cast('10' as int) as x, y from r1 where y<10)r1
> join r2 on r1.x=r2.x;
> Currently deterministic functions involving constants are ignored which
> results in missed transitive inference.
