Debug Info: include address-of ('&') operator and qualified names in template argument lists

This fixes several (7 out of 16) cases of PR14492 in the GDB 7.5 test
suite. It seems GDB was bailing out whenever it had even the slightest
problem with the template argument list (& I assume it didn't like
seeing template value parameters that were just simple names - perhaps
assuming that lone names must be types, not values)

Remove dependence on system headers from this test, to try to make the Windows bots happier.
