Currently maybeGuardInt32Index will always emit a index guard when called. This is too restrictive. For example currently we can't move tryAttachProxyElement after tryAttachTypedElement. This also prevents us from optimizing indexing with a string into primitive strings or magic arguments.

I tried this out before, but I don't like the way it turned out much. I am not sure arguments we should pass to the tryAttachXXX functions.
