Hoist static locals to module scope - #491

why? It's better to keep them inside the function to be closer to the original code.

int from_local_class() {
  static int x = 3;
  struct S {
    int get() const { return ++x; }
  };
  return S{}.get() + S{}.get();
}

S is already hoisted as module scope. Because of that it does not have access to the static variable. Hoist x at module scope so that S can have access to it.
