Committed this to branch. Thanks, Jitendra! 

Instead of maintaining a static list of vectorizable operator and expressions in Vectorizer
class, better way to do this is via adding an annotation on UDF and using that. We should
do that in a follow-up jira.

> Currently the query plan is vectorized at the query run time in the map task. It will
be much cleaner to add vectorization as an optimization step.
