History
Robin Burchell ca9ed9619f Improve performance of Qt::mightBeRichText by using QStringRef 
I noted this taking around 1% of QtQuick Text creation with a few simple bindings
which is quite considerable, so hopefully improvements here will add up gradually.

Also add a benchmark measuring changes:
