Change subject: IMPALA-7604: part 1: tests for agg cardinality ...................................................................... IMPALA-7604: part 1: tests for agg cardinality Add tests that demonstrate bugs with overflow and multiple aggregation classes and provide a baseline to demonstrate the effects of the bugfixes. Testing: Added planner tests: * Cardinality estimates with multiple groups (both grouping and non-grouping aggs). * Overflow case from multiplication of grouping expr cardinality. * Overflow handling of addition of multiple groups.
