I'm fine with that.  Note, though, that incorporating this potentially 
breaks quite some things.  In particular debugging and thunks.  Due to the 
hack for copying C++ classes also that will be broken.  I didn't get much 
feedback about the thing in general so I stopped for the time being, but 
at least some of the changes would also be usable for mainline.

It adds a uid2type map on top of Richis uid2decl map, which I think is 
also a nice thing to have in general.  But it has the same garbage 
collection implications as Richis uid2decl map, in that it will break 
bootstrap in mysterious ways, when something is collected between two 
aliasing passes :-/


Ciao,
Michael.
