    js: Adapt to misc API changes in SpiderMonkey 52
    
    - JS::InitSelfHostedCode() is now required to be called before the first
      global object is created.
    - js::GCMethods<T>::initial was moved from the friend API to the public
      API and renamed JS::GCPolicy<T>::initial.
    - JSPropertyDescriptor was renamed JS::PropertyDescriptor.
    - JS::CloneAndExecuteScript() now takes a return value parameter, even
      though we don't use it in this case.
    - js::DumpHeapComplete() was renamed to js::DumpHeap() and takes a
      JSContext parameter instead of JSRuntime.
