According to the dwarf standard pubnames and pubtypes for languages

like C++ should be the fully qualified names for the type.

Add a routine that does a language specific context walk to build
up the qualified name and use it when we add types/names to the
tables. Expand the gnu pubnames testcase as it's the most complex
to make sure that qualified types are also being added.
