Kris Mok 95e51ff849 [SPARK-23760][SQL] CodegenContext.withSubExprEliminationExprs should save/restore CSE state correctly ... ## What changes were proposed in this pull request? Fixed `CodegenContext.withSubExprEliminationExprs()` so that it saves/restores CSE state correctly. ## How was this patch tested? Added new unit test to verify that the old CSE state is indeed saved and restored around the `withSubExprEliminationExprs()` call. Manually verified that this test fails without this patch.
