  "message": "[StackIR] Optimize the simple case of a multivalue tee and extracts (#8623)\n\nWhen getting a multivalue from e.g. a call and then consuming it\nimmediately, we get this pattern:\n\n```wat\n      (tuple.extract 3 0\n        (local.tee $temp\n          (call $multivalue-return)\n        )\n      )\n      (tuple.extract 3 1\n        (local.get $temp)\n      )\n      (tuple.extract 3 2\n        (local.get $temp)\n      )\n```\n\nWe save the entire tuple to a local, then read index by index. In\nStackIR we can just remove all the tuple operations, as the value is on the\nstack and ready to be used.\n\nFixes #8618",
