[SPARK-7184] [SQL] enable codegen by default
In order to have better performance out of box, this PR turn on codegen by
default, then codegen can be tested by sql/test and hive/test.
This PR also fix some corner cases for codegen.
Before 1.5 release, we should re-visit this, turn it off if it's not stable
or causing regressions.
