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.
