[cfe-dev] Visiting implicit copy assignment

[Peter Stirling]

This is something that would also be useful for my clang tool (and I was 
planning to send an email to the list on it next week!).

Something like std::vector<Decl*> getImplicitDecls() would be very 
handy, without polluting the AST in a way that would confuse things that 
only care about what was in the source?
