Comment on attachment 389778 [details] Patch Lots of red bots. Are there parts of the JIT that needs to be changed to go with this change?

Nope, those are tests with expectations that rely on the deterministic order of HashTable iteration, which changes with this change. They just need rebasing. I can browse the web with asan enabled with this change, so the jit is fine.
