Seems like I can do what I want using -fdump-translation-unit-all
and then reading the .tu file to rebuild perl version of tree
and then traverse as I see fit.

There are one or two oddities in the file that I haven't figured out 
yet but looks promissing. Same technique should work for stub generator.

Oddities are that public/private-ness of base classes seems to get lost
and const-ness (qual:c) is confusing me.
