Christopher Channing 9ea5caf0ef IMPALA-2199: Row count not set for empty partition when spec is used with compute incremental stats ...

This patch resolves an issue where row count is not set to 0 when a partition spec is
used with 'compute incremental stats' on a partition that contains no data. The fix is
to populate the partition 'expected list' in the frontend with the partition spec, the
backend keeps track of which partitions had statistics generated. In the scenario where
no statistics are generated for a partition, the backend will fall back to the
'expected list' to zero out the statistics.
