I think we can get a SortMergeJoin paln with Cross, e.g. `select distinct
a.i + 1,a.* from T a cross join T t where a.i > 1 and t.i = a.i group by a.i
having a.i > 2`.

A test case to make the existing code fail.
@srowen I am sorry that this pull request is not well formatted but I just
want to help.
```scala
import org.apache.spark.sql.SparkSession
object Test extends App {
val spark =
SparkSession.builder().master("local").appName("test").getOrCreate()
import spark.sqlContext.implicits._
case class T(i: Int)
spark.sparkContext.parallelize(List(T(1), T(3),
T(3))).toDF.createOrReplaceTempView("T")
val in = "select distinct a.i + 1,a.* from T a cross join T t where a.i >
1 and t.i = a.i group by a.i having a.i > 2"
val sql = spark.sql(in)
sql.queryExecution.executedPlan.children.map { x =>
x.children.map { x =>
x.children.map { x =>
