[SPARK-5373][SQL] Literal in agg grouping expressioons leads to incorrect
result
`select key, count( * ) from src group by key, 1` will get the wrong
answer.
e.g. for this table
```
val testData2 =
TestSQLContext.sparkContext.parallelize(
TestData2(1, 1) ::
TestData2(1, 2) ::
TestData2(2, 1) ::
TestData2(2, 2) ::
TestData2(3, 1) ::
TestData2(3, 2) :: Nil, 2).toSchemaRDD
testData2.registerTempTable("testData2")
```
result of `SELECT a, count(1) FROM testData2 GROUP BY a, 1` is
```
[1,1]
[2,2]
[3,1]
```
