[SPARK-1610] [SQL] Fix Cast to use exact type value when cast from BooleanType to NumericTy...
...pe.
`Cast` from `BooleanType` to `NumericType` are all using `Int` value.
But it causes `ClassCastException` when the casted value is used by the following evaluation like the code below:
``` scala
scala> import org.apache.spark.sql.catalyst._
import org.apache.spark.sql.catalyst._
scala> import types._
import types._
scala> import expressions._
import expressions._
scala> Add(Cast(Literal(true), ShortType), Literal(1.toShort)).eval()
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Short
