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.
