It looks like this accidentally broke test compilation in branch-1.5; I'm 
hotfixing in #10478.

@rxin This PR incidentally also fixes another issue. Accessing a null 
element in an array of IntegerType erroneously returned 0:
```
scala> val df = 
sc.parallelize(Seq((Seq("val1",null,"val2"),Seq(Some(1),None,Some(2).toDF("s","i")
df: org.apache.spark.sql.DataFrame = [s: array, i: array]
scala> df.selectExpr("i[1]").collect()(0)
res1: org.apache.spark.sql.Row = [0]
```
It now correctly returns null.

[SPARK 12477][SQL] Tungsten projection fails for null values in array fields

Accessing null elements in an array field fails when tungsten is enabled.
It works in Spark 1.3.1, and in Spark > 1.5 with Tungsten disabled.

This PR solves this by checking if the accessed element in the array field 
is null, in the generated code.

Example:
```
// Array of String
case class AS( as: Seq[String] )
val dfAS = sc.parallelize( Seq( AS ( Seq("a",null,"b") ) ) ).toDF
dfAS.registerTempTable("T_AS")
