Vincent Tran d062257462 IMPALA-5494: Fixes the selectivity of NOT IN predicates

This change modifies the logic of NOT IN predicate so that
the planner can calculate the correct node cardinality. Prior
to this change, both IN and NOT IN predicates shared the
same selectivity, which resulted in the same cardinality
during planning.

The selectivity is calculated by the following heuristic:

selectivity = 1 - (num of predicate children /
                num of distinct values)

README

This directory contains Impala test workloads. The directory layout for the workloads should follow:

workloads/
   <data set name>/<data set name>_dimensions.csv  <- The test dimension file
   <data set name>/<data set name>_core.csv  <- A test vector file
   <data set name>/<data set name>_pairwise.csv
   <data set name>/<data set name>_exhaustive.csv
   <data set name>/queries/<query test>.test <- The queries for this workload
