Force initialize the runtime module in Module::genLLVMModule. It is required for all non-trivial D modules anyway, so why load it lazily? This fixes run/typeid_83.d (DtoDeclareTypeInfo expects runtime to be initialized)

module nested4;

void func(void delegate() dg) {
  auto v = (){
    dg();
  };
}

void main()
{
    func({});
}
