Well, DW_AT_name is unqualified.  But I would expect a qualified 
DW_AT_instantiated_name to look like a qualified name in .debug_pubnames.

Because the elements aren't individually named in the source?  If we 
have a TAG for the pack itself, we don't need to name the elements.  And 
doing it that way does seem cleaner than encoding this information into 
DW_AT_name, which I don't think happens anywhere else in DWARF.
