NOT IN predicate transformations

NOT IN lists are transformed into multiple predicates that use the <> operator.

<> predicates are not optimizable, but they are sargable. For example:

orig_airport NOT IN ('ABQ', 'AKL', 'DSM')


orig_airport <> 'ABQ'
AND orig_airport <> 'AKL'
AND orig_airport <> 'DSM'

In addition, large lists are sorted in ascending order for performance reasons.
