Key: ORC-443

Reporter: Fang Zheng
A few changes to ColumnWriter and its derived classes:
1. in add() function, re-order code to verify input parameters before modifying
any internal state.
2. in add() function, move the calls to colIndexStatistics->increase(1) out of
the loop. Many of those are virtual function calls.
