Abuse const_cast in QStringBuilder to get a little more performance
Without this const_cast, the call to QString::data() or
QByteArray::data() will cause a call to detach(), which is totally
unnecessary since we've just allocated data a couple of lines before.
Since we know we're the owner of the only reference, we can skip the
detach attempt.
