We should test the performance of the demangler, and we'll probably want to improve it.

The current setup has lots of memory allocations through the use of Box<...> for nested types and Vec<...> for name sequences. This original C++ code represented types as linked lists whose items were allocated in an arena, and apparently doing so improved performance a lot.
