> > 
> > With this patch, rather than embedding the JSReceiver address directly
> > in the WasmToJS wrappers, we put that in a fixed array with global handle
> > scope and instead embed the location of the handle and the index in the
> > wrapper. This ensures that the wrapper doesn't need to be patched if the
> > GC kicks in. This is needed to get the WASM code off the GCed heap.
