You can put them into ExtQualType, if they have to be on the type.  If  
you see how they handle address spaces or the GC attributes, you just  
copy those bits, and you're done.  The rest of the system works to  
make what needs to happen, happen.  If you don't need them on the  
type, they are already on the decl, just fetch the attributes from the  
decl, see:

           if (FD->hasAttr<NoReturnAttr>()) {
             NoReturnEdge = true;
             HasFakeEdge = true;

for example, in SemaDecl.cpp.
