d_print_comp with 1 level of recursion protection

This is the variant that allows 1 level of recursion (with an xxx ??? to why 1
level). Plus various symbols added to demangle-expected from PRs that used to
crash the demangler because of endless recursion.

The question now is whether this really is a good fix or if some of these
symbols really should demangle to something meaningful.
