D9236: Fill lists of default-constructed types directly, not append any by value

[Aaron Puchert]

  It might not actually be faster though, because you go through the memory twice. If the vector doesn't fit into the cache, that could introduce quite some slowdown.
  
  On the other hand, copying deep objects can obviously be costly. Some of the vector element types seem to carry around some baggage.
  
  The C++11 way would be to move such objects, can we do that? It seems to be supported via `QVector<T>::push_back(T&& t)`.
