Shouldn't this be in a wrapper somewhere?  Aren't we going to need to
demangle ObjC symbols in a lot of places where we demangle C++ symbols?

Objective-C is much simpler than C++ and has other ways to get things 
like class information (for instance), so this needs to be done in only 
a few places (Three, to be exact. Well, really, just two, and this is 
the second one).
