Host info used to be stored on the global reference underlying a Ref; now it is stored in a JSWeakMap and hence tied to the lifetime of the actual object on V8's heap. Additionally, the internal metadata needed for C-API functions is now stored on the SharedFunctionInfo and no longer overlaps with the host info mechanism.
