Many builtin objects that are prototypes forget to set their isPrototype bit

[Yusuke Suzuki]

For example, BooleanPrototype, DatePrototype, ErrorPrototype, FunctionPrototype etc. do not have `vm.prototypeMap.addPrototype(this)` setting phase.

[Geoffrey Garen]

Maybe we should move the responsibility for declaring prototypes into the Structure finishCreation function. That way, we're guaranteed to know about all prototypes.

Who calls addPrototype for DOM prototypes?

[Yusuke Suzuki]

prototypeMap is removed from the tree.

That doesn't remove the need to set their isPrototype bit.
