Add benchmark for pathological O(N^2) behavior in QQmlChangeSet.

This patch is just here for documentation of this behavior and does not
come with a fix yet. This hotspot was found while profiling the example
code attached to QTBUG-34391. It is triggered by the repeated calls
to _q_itemsMoved in QQmlDelegateModel::_q_layoutChanged.
