Put this inside an if (NOT ENABLE_ADDRESS_SANITIZER) so that we don't add it twice if both sanitizers are enabled. (ubsan is the only sanitizer that doesn't conflict with the other sanitizers. If we add more sanitizers in the future, we need to make sure to fail the build if conflicting sanitizers are enabled.)
