fef6f8eddc [js weak refs] Migrate the WeakRef parts into the new API 
New API is here: https://github.com/tc39/proposal-weakrefs/issues/55

The WeakCell parts stay in the old API, resulting in temporary code duplication
in some parts. Those parts will go away once the WeakCell-related parts are
migrated to the new API (but the spec needs some work first).

a51f3fc652 [js weak refs] Add WeakRef 
- Add the WeakRef class and its deref() function.

- Add WeakFactory.prototype.makeRef

- Implement the "keep during job" behavior for WeakRef constructor and deref().

- Here we keep the targets alive longer than until the end of the job
  (microtask), contradicting the spec. However, this is probably the indended
  behavior, see https://github.com/tc39/proposal-weakrefs/issues/39 .
