Currently this information is located in the

ModuleLoaderMap is generated at build time with the mapping of modules 
to loader. Once the VM initialized then there shouldn't be any further 
need for it and not clear that it would be worth exposing it in the API. 
Maybe you could expand a bit more on what you doing as it's hard to 
understand how you might use this.
