Opening a draft in preparation for when the 2021 edition is stabilized. This cannot be merged until the rustc side (rust-lang/rust#88100) hits nightly. |

Change `cargo fix --edition` to only fix edition lints. This changes it so that `cargo fix --edition` will only fix edition lints. The reason for this is that sometimes non-edition lints get in the way, and make suggestions that can cause failures. An example is a user that only ever runs `cargo test` or `cargo check --profile=test` locally, and doesn't realize there are problems with running without `cfg(test)` such as unused warnings. This works by using `--cap-lints=allow` along with `--force-warn` which takes precedence over `cap-lints`. This only works on nightly since `--force-warn` is still unstable. I will update this as part of #9800. Closes #5738

rust-lang/rust#88100 is merged, but due to some bors failures, it was only merged a few hours after nightly was released. So I guess we'll have to wait for the next nightly, in a bit more than 15 hours from now. |
|
If you rebase this on the master branch again, we could already bump the cargo submodule to this branch in the rust repository, if we don't want to wait. I think the tests will pass fine in that repository, without waiting for nightly, right? |

@alexcrichton This should be ready to go.
I would prefer to avoid bypassing the regular route here. Thanks, though! I'll take care of getting things merged tomorrow. |

Fix `cargo fix --edition` on stable. I accidentally missed the removal of a `-Zunstable-options` flag in #9800. This prevented `cargo fix --edition` from working on stable/beta.
This stabilizes the 2021 edition.
Closes #9781
