undname prints them, and the information is in the decorated name, so we probably shouldn't lose it when undecorating.
I spot-checked a few of the funnier-looking outputs, and undname has the same output.

$$Z appears between adjacent expanded parameter packs in the
same template instantiation. We don't need to print it, it's
only there to disambiguate between manglings that would otherwise
be ambiguous. So we just need to parse it and throw it away.

Template manglings use a fresh back-referencing context, so we
need to do the same. This fixes several existing tests which are
marked as FIXME, so those are now actually run.

This patch adds support for demangling r-value references, new
operators such as the ""_foo operator, lambdas, alias types,
nullptr_t, and various other C++11'isms.
There is 1 failing test remaining in this file, which appears to
be related to back-referencing. This type of problem has the
potential to get ugly so I'd rather fix it in a separate patch.
