I quickly brushed up the Optimizer code based on your advice:
Using `Stack`:
https://github.com/apache/spark/commit/a17d933aaad5c38a9d9ff20f978c1bad6c774fb1#diff-a1acb054bc8888376603ef510e6d0ee0R551
Using `tailrec`:
https://github.com/apache/spark/compare/master...maropu:SPARK-19951-3#diff-a1acb054bc8888376603ef510e6d0ee0R552
I checked the spark style-guide and I probably think we'd better to use
more readable one. So, `tailrec` is better? I'll submit the `tailrec` one after
this merged.
