SPARK-12898. Consider having dummyCallSite for HiveTableScan
Currently, HiveTableScan runs with getCallSite which is really expensive
and shows up when scanning through large table with partitions (e.g TPC-DS)
which slows down the overall runtime of the job. It would be good to consider
having dummyCallSite in HiveTableScan.
