AKA exactly the same as C++ overloaded functions, which are already
handled by the generic code.  I wish Ada didn't need its own copy of
the menu printing code - this (practical, I admit) habit of fixing
infrastructure issues in ada-lang.c make it already the largest source
file in GDB and getting larger.  It's got a good chunk of symtab.c
reimplemented already.

Again, this is the status quo, so I'm not going to rain on the
parade.  But in the long term this is a horrible maintenance mess.
