This is the only test in `jdk_loom` that fails without `-XX:-UseTLAB`. The test specifically looks for `ObjectAllocationOutsideTLAB` event, and there are lots of those events with `-XX:-UseTLAB`. We can fix the test to look for the event we actually want.
This depends on [JDK-8297491](https://bugs.openjdk.org/browse/JDK-8297491) that fixed Loom code to actually disable TLABs.
Additional testing:
- [x] Affected test with `-XX:+UseTLAB` and `-XX:-UseTLAB`
