Description
EqualNullSafe for FloatType and DoubleType might generate a wrong result by codegen.
scala> val df = Seq((Some(-1.0d), None), (None, Some(-1.0d))).toDF()
df: org.apache.spark.sql.DataFrame = [_1: double, _2: double]
scala> df.show()
+----+----+
| _1| _2|
+----+----+
|-1.0|null|
|null|-1.0|
+----+----+
scala> df.filter("_1 <=> _2").show()
+----+----+
| _1| _2|
+----+----+
|-1.0|null|
|null|-1.0|
+----+----+
The result should be empty but the result remains two rows.
