These functions are just thin wrappers around classList now. We should use classList cirectly instead of these functions.
I did TreeOutline in r101313 because I had done it internally on a copy we use in Safari and I upstreamed our changes. We should do the rest of the Inspector next!

I think reducing out own wrappers is a good idea, especially if they are so thin as these are. We should also remove Function.prototype.bind, which is native in JSC at least not sure about V8.
