[demangler] Update node match calls

Each demangler node's match function needs to call the provided
functor with constructor arguments.  That was omitted from D120905.
This adds the new Precedence argument where necessary (and a missing
boolean for a module node).

The two visitors need updating with a printer for that type, and this
adds a stub to cxa_demangle's version.  blaikie added one to llvm's.
I'll fill out those printers in a followup, rather than wait, so that
downstream consumers are unbroken.
