[SPARK-22551][SQL] Prevent possible 64kb compile error for common expression types

[viirya]

What changes were proposed in this pull request?

For common expression types, such as BinaryExpression and TernaryExpression, the combination of generated codes of children can possibly be large. We should put the codes into functions to prevent possible 64kb compile error.

How was this patch tested?

Added test.

Could you add a test case?

[viirya]

@kiszk I added a test. But I think after #19767 is merged, the generated codes will be changed too. I may need to adjust the test case after that.

I can't reproduce the issue after #19767 is merged. Hopefully it solves this issue too, so I will close this. If not and I can reproduce it later, I will re-open this.
