    Original change's description:
    > [builtins] Move most WeakMap/WeakSet code from JS to C++ builtins
    > 
    > They were already implemented mostly in C++ (only error/negative
    > cases were handled in script), so this is mostly just a cleanup.
    > Only the constructors remain in script after this CL.
