[SPARK-17702][SQL] Code generation including too many mutable states
exceeds JVM size limit.
## What changes were proposed in this pull request?
Code generation including too many mutable states exceeds JVM size limit to
extract values from `references` into fields in the constructor.
We should split the generated extractions in the constructor into smaller
functions.
## How was this patch tested?
I added some tests to check if the generated codes for the expressions
exceed or not.
