And thanks to Andrew Haley for noticing that this is not desirable
for the "weak" versions that can spuriously fail. The C++ versions
both report boolean and set one of the arguments by-ref to hold
value, which we can't do. So I reverted these three (but renamed
weakCompareAndSet to weakCompareAndSetRelaxed for clarity).
