RFC: Deprecating class posing

[David Chisnall]

Hi Everyone,

With the non-fragile ABI, Apple removed support for class posing.   
This makes sense, because it's no longer possible to guarantee that  
the class has the same ivar layout.

I'm tempted to do the same thing for our non-fragile ABI.  This has  
the added advantage that you could then statically export class names  
as linker symbols, which would make class messages a lot faster (you'd  
no longer need to do the lookup each time, and all of the ugly stuff  
in GNUstep where the class pointer is cached could go away).

Any objections?

David
