c++/9450: incorrect mangled name for scope resolution template argument

gcc generates exactly the same mangled name for these 2 testcases

// ----------------- t1 --------------------
struct A5 {int i;};
template <int A5::*p> void f5(int) {}

template <class T>
void g5() {f5<&T::i>(0);}

int main(void)
{
   g5<A5>();
}
// ----------------------------------------

name:
_Z2f5IXadsr2A5NS0_1iEEEvi

// ---------------- t2 --------------------

struct A5 {int i;};
template <int A5::*p> void f5(int) {}
void g5() {f5<&A5::i>(0);}

// ----------------------------------------

name:
_Z2f5IXadsr2A5NS0_1iEEEvi
