auto-unexpected-qstringbuilder

Finds places where auto is deduced to be QStringBuilder instead of QString, which introduces crashes. Also warns for lambdas returning QStringBuilder.

Example

#define QT_USE_QSTRINGBUILDER
#include <QtCore/QString>
(...)
const auto path = "hello " +  QString::fromLatin1("world");
qDebug() << path; // CRASH
