On AIX, we use __atexit to register dtor functions rather than __cxa_atexit. So a driver change is needed to default AIX to using -fno-use-cxa-atexit. Windows platform does not uses __cxa_atexit either. Following its precedent, we remove the assertion for when -fuse-cxa-atexit is specified by the user, do not produce a message and silently default to -fno-use-cxa-atexit behavior.
