refactoring for toplevel-ref, toplevel-set, link-now

Browse source 
* libguile/vm-i-system.c (toplevel-ref, toplevel-set)
* libguile/vm-i-loader.c (link-now):
* libguile/vm.c (resolve_variable): Factor out common code to a static
  method. The compiler can still inline it, so it shouldn't have a
  significant performance effect.

* libguile/vm-engine.c (vm_error_no_such_module): Remove now-unused
  label.
