        This patch does two things:
        
        * It adds a toJSNewlyCreated function for creating JS wrappers for nodes where we know
        that the node doesn't have a wrapper. This avoids a hash lookup.
        
        * It adds toJSNewlyCreated methods for JSElement and JSText. 
        
        All in all this is a 4.3% speedup on Acid 3 test 26.
