Initially, I tried it. The behavior is controlled by the configuration
`SQLConf.MAX_CASES_BRANCHES`. However, I am not sure how to change the default
conf value of `SQLConf.MAX_CASES_BRANCHES` in `OptimizeCodegenSuite`.
At the same time, we do not have a test case to verify the configuration
`MAX_CASES_BRANCHES`.
That is why I added the test case here. Let me know if you have any idea.
Thanks!
