I wrote these tests for my IMPALA-3987 patch, but other issues block that optimisations. These tests exercise an interesting corner case so I split them out into a separate patch. The functional tests exercise every join mode for nested loop join and hash join with an empty build side. The perf test exercises hash join with an empty build side. Testing: Made sure the tests passed with both partitioned and non-partitioned hash join implementations. Ran the targeted perf query through the single node perf run script to make sure it worked.
