Represent the unevaluated exception specification of an implicitly
declared or deleted function with a simple placeholder, not a list
of functions.

Before then GCC errors out with:

pr84698.C: In instantiation of ‘struct X’:
pr84698.C:15:14:   required from here
pr84698.C:7:14: error: declaration of ‘template void
swap(X&, X&) noexcept ()’ has a different
exception specifier
  friend void swap(X& a, X& b) noexcept(noexcept(a.swap(b)));
  ^
pr84698.C:11:13: error: from previous declaration ‘template
void swap(X&, X&) noexcept (noexcept (a.swap(b)))’
 inline void swap(X& a, X& b) noexcept(noexcept(a.swap(b))) {
