The self-hosted aarch64 backend is not currently functional due to the Liveness changes. A previous commit disabled aarch64 on the behavior tests; this commit disables it and arm for the test cases. Moreover, all incremental test cases have been unified into shared cross-platform cases, which can be gradually enabled as the backends improve.
