You could certainly expand 

  new A;

into

  __call_and_construct_A ();

COMDAT A* __call_and_construct_A () {
  return {normal code for new A};
}

Whether or not you call this function a constructor is of little
importance, though I suppose emitting it with the other constructors might
improve locality.
