QSet deprecation warning for range loops

When using range loops with a QSet a warning pops up complaining about deprecated operator --.

Example:

QSet<int> test;
for(const auto &t : test) {
}

C:\Qt\5.15.0\msvc2017_64\include\QtCore/qset.h(177): warning C4996: 'QHash<T,QHashDummyValue>::const_iterator::operator --': was declared deprecated

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.24.28314\include\xutility(1591): note: see reference to function template instantiation 'QSet<T>::const_iterator &QSet<T>::const_iterator::operator --(void)'
