// Lets items opt out of coverage instrumentation via
// `#[cfg_attr(coverage_nightly, coverage(off))]`, which we put on every
// `#[cfg(test)]` module so that reported numbers describe the code we ship
// rather than the tests exercising it. `coverage_nightly` is set only by
// cargo-llvm-cov on nightly (see `cargo cov` in .cargo/config.toml), so stable
// builds never see the unstable feature.
