[Bug c++/29773] New: name mangling for nested functions is wrong

["geoffk at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Given the following translation unit:

inline int (*foo())()
{ 
  struct localstruct  {
    static int f() {
      return 3;
    }
  };
  return localstruct::f;
}

GCC mangles foo::localstruct::f as '_ZZ3foovEN11localstruct1fEv'.

According to the C++ ABI (see especially the third example in section 5.1.6) it
should be

_ZNZ3foovE11localstruct1fEv

That is, it should be <function name> <bare-function-type> at the top level,
not a <local-name>.

This is of course an ABI-breaking change.
