Created an attachment (id=650)
sort hacky move of demangle from phobos to druntime and hook into the
stacktrace code

Arguably the demangler belongs in the runtime.  The current code is, well, less
than ideal.  At least from an interface standpoint.  But this get's the pieces
moved and put together to demonstrate what it could be.  In the process I also
noticed that the current unittest for druntime fails, which is handy for
testing.  The results:

<snip a bunch of foo unittest lines>

vs what it emitted before the changes:
