+ci: `native_owned_typed_views` accepts `control_flow` as a missed-vectorization reason (#8489). Three of its loops began reporting that reason on the Linux/release configuration the `compiler-output-regression` gate runs in, failing one of `full-suite-gate`'s required jobs. It is pre-existing (identical on the pre-merge baseline `3627657c7`, and still present after #8484 reverted the `extern "C-unwind"` conversions) and not reproducible on a macOS `perry-dev` build. The workload requires no vectorization — `min_vectorized_loops = 0` with an explicit scalar baseline — so this list is a change detector, and its sibling workloads already accept the same reason. #8489 stays open to attribute the codegen change behind it.
