This is a fairly common attribute on methods, but is not something you need to know when reading the method docs - the purpose of the attribute is for the compiler to tell you about it if you forget to use a value. Removing reclaims some valuable space in the summary of methods.

Improve CTFE UB validation error messages As mentioned in rust-lang#86245 (comment) this PR slightly improves the formatting of validation errors, to move the path to the error prefix. From: `type validation failed: encountered invalid vtable: size is bigger than largest supported object at .0` To: `type validation failed at .0: encountered invalid vtable: size is bigger than largest supported object`.
Remove must_use from ALLOWED_ATTRIBUTES This is a fairly common attribute on methods, but is not something you need to know when reading the method docs - the purpose of the attribute is for the compiler to tell you about it if you forget to use a value. Removing reclaims some valuable space in the summary of methods, particularly when the attribute has a long string value. As discussed in rust-lang#84309. Partially addresses rust-lang#81482. r? `@Manishearth`

Stabilize {std, core}::prelude::rust_*.
This stabilizes the `{core, std}::prelude::{rust_2015, rust_2018, rust_2021}` modules.
The usage of these modules as the prelude in those editions was already stabilized. This just stabilizes the modules themselves, making it possible for a user to explicitly refer to them.
