This revision is now accepted and ready to land.

Here's a testcase that produces a name with external linkage:

  struct X { int i, j; };
  auto [a,b] = X{1,2};
  template<typename T> void f(decltype(a + T())) {}
  template void f<int>(int);

We should make sure that we mangle the reference to `a` as `_Z1aE` here.
