Review comment:
The set property of this variable is used at couple of places in
SortMergeJoin
([here](https://github.com/apache/spark/blob/3fdfce3120f307147244e5eaf46d61419a723d50/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/SortMergeJoinExec.scala#L122),
[here](https://github.com/apache/spark/blob/v3.0.0/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/SortMergeJoinExec.scala#L149)).
We can use ExpressionSet maybe at those 2 places and make it a Seq in
constructor here. any thoughts?
