Description

(discussion about this ticket started in CALCITE-4094)

Strong.Policy and NullPolicy are two different enum that represent grosso-modo the same thing. The former is mostly used on the simplifier, and the latter on the code generation.
To be studied if we could unify both entities and make it available through the SqlOperator.
