benchmark added, the result is included in the benchmark code. I also ran
this benchmark against master branch, the result is:
```
Java HotSpot(TM) 64-Bit Server VM 1.8.0_60-b27 on Mac OS X 10.11.4
Intel(R) Core(TM) i7-4960HQ CPU @ 2.60GHz
Dataset.map: Best/Avg Time(ms) Rate(M/s) Per
Row(ns) Relative
-------------------------------------------------------------------------------------------
scala function 2471 / 2531 4.0
247.1 1.0X
java function 2416 / 2478 4.1
241.6 1.0X
```
So with whole stage codegen, we can get about 2.5 times speed up!
