Can't do that and preserve the abi, also, there is no concept in gcc  
currently to so name it, and what's worse, in general, it is just  
impossible given how people use gcc.  You'd require that the decision  
of which shared library a compilation unit is to go into be fixed  
before compilation, currently, that isn't so required.

All in all, we should just agree to not worry about non-merged  
typeinfo name, or remove support for it.
