Reviewed by Yusuke Suzuki.

Optimize createJSHTMLWrapper() by using a switch statement and leveraging the
fairly recently added ElementName enumeration.

The previous code was relying on a HashMap which has some extra cost associated
with hashing and dealing with hash collisions. It also relied on function
pointers which made inlining harder.
