Subject: QREMatchIterator: add support for range-based for

Add begin()/end() on QRegularExpressionMatchIterator, making
iterators over an iterator (like directory_iterator).

[ChangeLog][QtCore][QRegularExpression] The iterator object
(QRegularExpressionMatchIterator) returned by a global match
is now usable in a range-based for loop.
