I'm not sure when the new demangler will be ready, so you can either
ask David (cc:ed) about it, or for a short-term solution implement the
missing features in libcxxabi and backport to LLVM.
The work is not entirely wasted as we gain new testcases to use when
we'll switch to the new demangler. I understand backporting isn't a
lot of fun but considering the two implementations are supposed to be
in sync (and if they're not, that should be fixed), it shouldn't be a
lot of work.
