When no index can be used on a INNER JOIN and there's a relation setup between X and Y
then a MERGE should be performed. Test with selectable Stored Procedure.
FBTEST: functional.arno.optimizer.opt_inner_join_merge_06
NOTES:
[08.04.2022] pzotov
FB 5.0.0.455 and later: data source with greatest cardinality will be specified at left-most position
in the plan when HASH JOIN is choosen. Because of this, two cases of expected stdout must be taken
in account, see variables 'fb3x_checked_stdout' and 'fb5x_checked_stdout'.
