Consider:
```
$ cat /tmp/a.ii
struct S {};
struct T {
S Foo(S);
S Get(S);
};
S T::Get(S key) {
[[clang::musttail]] return Foo(key);
}
$ clang -cc1 -triple aarch64-pc-windows-msvc19.34.0 -emit-obj /tmp/a.ii
fatal error: error in backend: failed to perform tail call elimination on a call site marked musttail
```
(Other aarch64 triples, such as aarch64-unknown-unknown, work.)
