Somewhat off the cuff, but I think it would be nice if commandline object
inspection tools could query for a particular symbol when the user
specified it in the C++, unmangled form.

Generally, it seems useful to unify the mangling and unmangling code if
only so that we constantly round-trip test both halves and don't end up
with divergences.
