regression: lacking of ifndef QT_NO_DEBUG_STREAM wrapper causes compile problem

In certain circumstances, the following line causes compile problem:
src/gui/styles/qstyle.h
Q_GUI_EXPORT QDebug operator<<(QDebug debug, QStyle::State state);

src/gui/styles/qstyleoption.h
Q_GUI_EXPORT QDebug operator<<(QDebug debug, const QStyleOption::OptionType &optionType);
Q_GUI_EXPORT QDebug operator<<(QDebug debug, const QStyleOption &option);

Possible resolution is adding a wrapper:
#if !defined(QT_NO_DEBUG_STREAM) && !defined(QT_NO_DEBUG)
Q_GUI_EXPORT QDebug operator<<(QDebug debug, QStyle::State state);
#endif
