Add the rest of the non-volatile members of std::atomic to QBasicAtomic

[ChangeLog][QtCore][Atomic support]Added more operations to the atomic
classes, including operator T(), operator=(T), operator++,
operator--. For the QAtomicInteger, bit-manipulation operations are
also provided, both in operator and in fetchAndXxxYyyyyy modes.
