Parse error ;)  If we apply the patch I provided with the failing
testcase DECL_NAME would be different from now and we use DECL_NAME
to generate DW_AT_Name and friends.  At least for the dwarf entries
where we do not have a mangled name also (all the types), we need
something better than just the base name of the template (at the
moment we have the complete "diagnostic" name here).
