Pull out common conjuncts from disjunctions

Details

    Description

      I see this in tpch and tpcds where predicates look like this:

      where
      ( col = 1 AND ... AND ...) or
      ( col = 1 AND ... AND ...) or
      ( col = 1 AND ... AND ...)

      It's an OR of ANDs and there are predicates that are in each OR (col = 1). This could be pulled out.
