Instead of maintaining a list that is poorly kept in sync we can just use the attribute.

When was this attribute introduced in rust? If it's been there for a few stable releases then that's fine, we generally don't try to support toolchains older than ~3 releases |

It's rust-lang/rust#100719 which has only been merged about 4 months ago, so that's not that many stables yet. But since this touches intrinsics, people that are impacted by this will use nightly (or the beta bootstrap compiler in core/std itself, which is why I wanted to implement this in the first place). |

Ye, that seems fine to merge now then imo 👍 |

minor: remove unused known `Name`s After #13866, known `Name`s for safe intrinsics are no longer used and thus should be removed.

This will make new RA versions unusable with old toolchains that don't have the attribute yet. Should we keep maintaining the list as a fallback or just don't care?
