Bugzilla

Matt, can you try this again on your machine with [this JS shell build](https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/DdMz12eVSKyW_wsC-gCz4Q/artifacts/public/build/target.jsshell.zip) and the `--tbpl` flag passed to jit-tests? So something like:
```
$ python3 js/src/jit-test/jit_test.py downloaded/build/js  --tbpl bug1940716 --repeat 100
```

(It's the shell build from [this try push](https://treeherder.mozilla.org/jobs?repo=try&group_state=expanded&revision=560791b6516d049f18a550798536a364db5cd7b7), for the "OS X Cross Compiled Shippable" Bpgo(B) job, since that's the one we end up running according to the logs.)
