Right.  It didn't.  But, DECL_DESTRUCTOR_P was something like:

  DECL_DESTRUCTOR_NAME (...) && DECL_LANGUAGE (...) == lang_cplusplus

And DECL_LANGUAGE gets set to C for a member function in a struct in
an extern "C" block.  I don't know what to think of that.

Anyhow, it's much cleaner to have DECL_DESTRUCTOR_P just set a bit.
For example, Alex's new-ABI mangling code then has only a single entry
point; not the two separate ones we have now.  Someday, we might even
be able to do lazy mangling -- that would save some space/time.  But,
we still need to be able to tell what's a destructor and what's not.
