This patch makes it possible to generate the code cache for the builtins directly from the original script object (instead of compiling a new one) and after the script has been run (via `NativeModule.require`). Before this patch only the top level functions (the wrapped ones) are included in the cache, after this patch the inner functions in those modules will be included as well. Also blacklists modules from dependencies like V8 and node-inspect since we cannot guarantee that they are suitable to be executed directly.
