Fix to make g++-10.2 happy
g++-10.2 fails to compile qregion.cpp in RelWithDebInfo configuration,
with error message:
qregion.cpp:3617:12: error: ‘ET.EdgeTable::ymax’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]
g++ is right here, for Count==1, 'ET' is not initialized but used.
This patch fixes this by Q_ASSUMEing Count > 1.
Pick-to: 5.15
