PS3, Line 892: ++num_values_;
We already keep track the number of values in the column writer. I think it's 
better to only keep track it at one place, as it is simpler and less 
error-prone.

Probably you could move the num value tracking to ColumnStats only, so the col 
writer wouldn't track it on its own.

Or only track num values here, and pass col_writer->num_values() to 
GetIcebergStats().
