------------------------------------
[~jcamachorodriguez] [~ashutoshc] Can you take a look? Review request:
https://reviews.apache.org/r/69215/
Updated tests have the following changes:
* Join re-ordering
* Missing LEFT semi join or addition of LEFT Semi join
I have verified that the change in results is just ordering.
> Join reordering may not be triggered if all joins in plan are created by
> decorrelation logic
