The patch uses the weak version of compare_exchange universally, which
is incorrect in a number of cases. You wouldn't see this on x86_64;
you'd have to use a ll/sc target such as powerpc.
In addition to changing several uses to strong compare_exchange, I
also optimize the idiom

which I plan to finish as a separate patch once I am back from the ISO
C++ meeting.
tested x86_64/linux
