SafeStack is a stack protection technique implemented in llvm. It is enabled with a -fsanitize flag. iotests are currently disabled when any -fsanitize option is used, because such options tend to produce additional warnings and false positives. While common -fsanitize options are used to verify the code and not added in production, SafeStack's main use is in production environments to protect against stack smashing. Since SafeStack does not print any warning or false positive, enable iotests when SafeStack is the only -fsanitize option used. This is likely going to be a production binary and we want to make sure it works correctly.
