> After HIVE-21001 some selectExpressions will start using VectorUDFAdaptor for "null and
x" expressions. Because right now there are 2-3 places from which rewrite will be done to
the form of "null and/or x" form; it would be better to support it.

> selectExpressions: VectorUDFAdaptor((null and dt1 is null))

> usesVectorUDFAdaptor: true
> [...]
> {code}
