QHeaderView: apply small optimization in recalcSectionStartPos()
The loop in recalcSectionStartPos() calls QVector<>::constEnd() after every iteration which is not needed since the vector stays constant. Therefore use the new for loop syntax from c++11 so constEnd() is only called once which gives a small speedup, noticeable with large section counts.
