History
Andrey Semashev 9fd085c59f Added negate_and_test and complement_and_test ops. 
As the names suggest, the methods perform the corresponding operation and test
if the result is not zero.

Also, for the emulated fetch_complement, take care of integral promotion, which
could mess up the storage bits that were not part of the value on backends
where the storage is larger than the value. This could in turn break CAS on
the atomic value as it compares the whole storage.
