  Log:
    mjit.c: add class serial of singleton class
    
    for toplevel self.
    
    Toplevel self's class is not `Object` but `#<Class:Object>`.
    This commit allows to inline method call setup for toplevel methods.
    I've thought r63053 works but it doesn't...
    
    I actually want to add all singleton classes but I'm not sure what's the
    good way for it. I assumed that using ObjectSpace.each_object is suboptimal.
