Currently we reject sargable node merging if either one of them has a non-trivial disjunction (see intersectPartialSchemaReqMap).

We may however have cases say with 3 sargable nodes where the first and last ones are trivial disjunctions while the middle one is not, and thus do not merge any of them.

We should add a rewrite to optionally reorder sargable nodes to support the best merging strategy.
