Rollup merge of #121658 - jieyouxu:ice-outdated-nightly, r=oli-obk
Hint user to update nightly on ICEs produced from outdated nightly This is a conservative best-effort approach to detect a potentially outdated nightly; it will fallback to the regular ICE-reporting if any of the following cases are true: - Channel is not nightly - Version information is not available - Version date is not parseable as a YYYY-MM-DD or is missing - System time is at least 36 hours ahead of the user's nightly release datetime. - Any internal features are used. Note that I'm not sure how to make a test for this: I tested this manually by `CFG_VER_DATE="2020-02-02" ./x build library --stage 1`, and also changing the channel detection in `rustc_driver_impl` from `Some("nightly")` to `Some("nightly" | "dev")`, and then running `rustc +stage1 test.rs -Ztreat-err-as-bug=1` with a non-existent `test.rs`. <img width="1145" alt="Screenshot 2024-02-27 at 01 12 28" src="https://github.com/rust-lang/rust/assets/39484203/eff6af2e-4b19-4a70-af57-cd739ecf0e84"> Closes #118832.
