It seems like this patch causes clang to accept the following code when compiled with -std=c++11. Is this the expected behavior? Shouldn't the compiler reject the code if it's not compiled with -std=c++17 or newer?

$ cat test.cpp

  #include <new>
  
  void *p;
  
  int main()
  {
    operator delete(p, (std::align_val_t)256);
    return 0;
  }

$ clang++ -std=c++11 test.cpp
