Nowadays if CSS2PropertiesPrototype or similar ends up to CC graph,
it adds quite some edges. Lots of getters and setters.
Defining those lazily should help.

Hmm. We could, of course, give all the new bindings protos resolve hooks and define properties lazily. The question is whether there are perf costs for that. Especially for cases (very common with CSS2Properties) where lots of expandos are set on the objects. Or do we disable the missing-property IC here anyway because of the proxy?

Proxies disable the missing-property IC.
