clang-cl fails to compile foo.cc below on C++17 mode.

---- foo.cc
struct Foo {
  virtual void f();
  virtual void g();
};

void Foo::f() {}
void Foo::g() {}

template <void (Foo::*)()>
void h() {}

void x() {
  h<&Foo::f>();
  h<&Foo::g>();
}
----
$ clang-cl /c /std:c++17 foo.cc
foo.cc(10,6):  error: definition with same mangled name as another definition
void h() {}
     ^
foo.cc(10,6):  note: previous definition is here
1 error generated.
----

Specifically in our code, V8Console::call<> instantiations are this pattern.

I'm not sure it's related, but https://bugs.llvm.org/show_bug.cgi?id=27066 may be related.
