My bias would be toward designing an interface which is at least
slightly better.  In particular, I'm not sure the arrays should be
exposed as arrays.

I gather that the main thing you need is the ability to generate
arbitrary mangling trees, and the ability to print the demangled
string corresponding to such a tree.

Changing the demangler output is not a major compatibility issue.
Ideally any changes from here on out should be reflected in the
libiberty testsuite, so that we at least don't change them
accidentally.
