- The attribute is behind a feature gate.
- Error if both #[naked] and #[track_caller] are applied to the same function.
- Error if #[track_caller] is applied to a non-function item.
- Error if ABI is not "rust"
- Error if #[track_caller] is applied to a trait function.

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.
