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.
