branches.
For example, in the above URL, we can say the condition at line 45 is
always false since the result of map() is never null by using our schema.
As a result, we can eliminate assignments at lines 52 and 56, and
conditional branches at lines 55 and 61.

This problem can be reproduced at commit id

I just realized it since it broken a build with Scala 2.10.

I can reproduce the problem in SPARK-15285 with master branch.
Should we reopen SPARK-15285?
