Takuya UESHIN 8e37ed6eb8 [SPARK-1608] [SQL] Fix Cast.nullable when cast from StringType to NumericType/TimestampType. ... `Cast.nullable` should be `true` when cast from `StringType` to `NumericType` or `TimestampType`. Because if `StringType` expression has an illegal number string or illegal timestamp string, the casted value becomes `null`.
