[Bug c++/31445] New: [4.3 regression] type_argument_pack not supported by dump_type

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

More fallout from the variadic templates on mainline:

===========================================================
template <typename... T> struct A
{
  void foo(T...);
  A(T... t) { foo(t); }
};

A<int> a(0);
===========================================================

This is only a diagnostic problem in the second to last line:

bug.cc: In constructor 'A<T>::A(T ...)':
bug.cc:4: error: parameter packs not expanded with `...':
bug.cc:4: note:         't'
bug.cc: In constructor 'A<T>::A(T ...) [with T = int]':
bug.cc:7:   instantiated from here
bug.cc:4: error: no matching function for call to
'A<int>::foo(#'type_argument_pack' not supported by dump_type#<type error>)'
bug.cc:3: note: candidates are: void A<T>::foo(T ...) [with T = int]
