• Do not create a HiveSortLimit operator when hive.orderby.position.alias is disabled and the Order by clause of the query has integer constants as keys. Also ignore the constants as keys when there are both column references and constant keys.
• Do not create HiveSortExchange operator when both field collaction and distribution keys are all constants and hive.orderby.position.alias is disabled. Also ignore the constants as keys when there are both column references and constant keys.

Why are the changes needed?

To synchronize the Order/Sort/Distribute/Cluster by behaviors when hive.orderby.position.alias is disabled and CBO is enabled/disabled .

Does this PR introduce any user-facing change?

Yes, the results of queries with Order/Sort/Cluster by clauses may have different order.
