Possibly.  We search for the canonical form in the symbol table, which
means we need to canonicalize before adding them to the (partial, full,
maybe minimal also) symbol table.  The trick will be delaying the
add-to-symbol-table until the symbol is needed, using a clever trick
suggested by Ian - keeping a list of pending symbols by basename,
basically.

There are some complications.  Particuarly, the code to infer classes'
fully qualified names depends on having the canonical demangled name
available.  I may be able to do something about this but I'm not sure
what yet.
