Can we make the check work without introducing `TK_AsIs`?
I understand that it was needed for templates but we had previously working templates in
```
template <typename T>
void m(const std::vector<T> &v) {
  return &v[0];
  // CHECK-MESSAGES: :[[@LINE-1]]:10: warning: 'data' should be used for accessing the data pointer instead of taking the address of the 0-th element [readability-container-data-pointer]
  // CHECK-FIXES: return v.data();
}
```
