-------------------------------------
Summary: Loosen nullability if the cast is force-nullable.

URL: https://issues.apache.org/jira/browse/SPARK-25096
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.0
Reporter: Takuya Ueshin
In type coercion for complex types, if the found type is force-nullable to
cast, we should loosen the nullability to be able to cast. Also for map key
type, we can't use the type.
