There are some tests in the rustfmt test suite that are ignored by default. I believe these tests are ignored because they have caused issues with the the `rust-lang/rust` test suite. However, we recently experienced an issue (5395) that would have been avoided had these tests been running. With the introduction of the new `#[rustfmt_only_ci_test]` attribute macro we can run these tests when the `RUSTFMT_CI` environment variable is set, which will presumably only be set during rustfmts CI runs. When the environment variable is not set the `#[rustfmt_only_ci_test]` will be replaced with an `#[ignore]`.
