Make `Cell::new` method come first in documentation
Methods to create a thing usually comes first in `std` documentation, and `Cell` has been an exception. Also, `T: Copy` specialized methods should not be on top of the page. (This had led me to miss that most of its methods are not bounded by `Copy`...)
rewrite documentation for unimplemented! to clarify use
The current docs for `unimplemented!` seem to miss the point of this macro.
> This can be useful if you are prototyping and are just looking to have your code type-check, or if you're implementing a trait that requires multiple methods, and you're only planning on using one of them.
You could also return a `()` if you just want your code to type-check.
I think `unimplemented!` is useful for when you want your program to exit when it reaches an unimplemented area.
I rewrote the explanation and gave examples of both forms of this macro that I think clarify its use a little better.
Only add sanitizer runtimes when linking an executable (#64629).
This change modifies the code to only add sanitizer runtimes if we are linking an executable, as those runtimes should never be part of libraries. I successfully compiled `mozilla-central` with ASan using this patch.
Update reference
- Add macros in extern blocks and new proc-macro support.
- Update for "modern" `meta` matcher.
- Update await desugaring after rust-lang/rust#64292
remove event that causes panics in measureme tools
the measureme tools summarize and crox do not alow a event to go out of scope of the parent event
codegen_and_optimize_crate ends after the codegen_crate event

Add feature gate for raw_dylib.
This PR adds the feature gate for RFC 2627 (https://github.com/rust-lang/rust/issues/58713). It doesn't contain the actual functionality.
Add I'm not sure whether i did it correctly, since this is the first time i did this.

Add support for `const unsafe? extern fn`
This works just as you might expect - an `const extern fn` is a `const fn` that is callable from foreign code.
Currently, panicking is not allowed in `const`s. When https://github.com/rust-lang/rfcs/pull/2345 (https://github.com/rust-lang/rust/issues/51999) is stabilized, then panicking in an `const extern fn` will produce a compile-time error when invoked at compile time, and an abort when invoked at runtime.
Since this is extending the language (we're allowing the `const` keyword in a new context), I believe that this will need an FCP. However, it's a very minor change, so I didn't think that filing an RFC was necessary.
This will allow libc (and other FFI crates) to make many functions `const`, without having to give up on making them `extern` as well.

Remove dead module
This module is not referenced any more. (A quick audit didn't show other stale files like this, so presumably this is the only one.)
Use shorthand initialization in rustdoc
This just fixes a few lints I rust-analyzer was showing. Is this sort of PR useful? Should the lints be fixed as apart of the otherwise unrelated PR I was working on?
Optimize integral pattern matching
Various improvements to integral pattern matching. Together they reduce instruction counts for `unicode_normalization-check-clean` by about 16%.
