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.
llvm-svn: 339275
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.
