Allow resetting the default statement class to PDOStatement

Currently HHVM strictly enforces that the statement class be a descendent of PDOStatement. While the PHP Documentation states that it has to be a subclass, I believe this is subclass in the sense implied by Liskov's OO substitution principle. Thus, the PDOStatement class should be accepted.

Zend does accept the PDOStatement class without warning or notice.
