Summary: Fold CASE into NVL when CBO optimized the plan
Key: HIVE-13637

Project: Hive
Issue Type: Sub-task
Components: CBO
Affects Versions: 2.1.0

After HIVE-13068 goes in, folding CASE into NVL got disabled when CBO has
optimized the plan, as it was done by ConstantPropagate in Hive. We need to
enable it back.
