etc: Add sample rust-analyzer configs for eglot & helix
LSP configuration in editors like Emacs (eglot) and helix does not
use the same JSON format as vscode and vim do. It is not obvious
how to set up LSP for rustc in those editors and the dev guide currently
does not cover them. Adding sample configuration files for those editors
alongside the currently existing JSON one would be helpful.
I figured having those included in the repo like the JSON one might save
someone some time and frustration otherwise spent on trying to get the
more niche editors' LSP to work properly. I'll add a section in the dev
guide too.
Cleanup some known-bug issues
I went through most of the known-bug tests (except those under `tests/crashes`) and made sure the issue had the `S-bug-has-test` label and checked that the linked issue was open. This is a bunch of cleanups, mainly issues that have been closed and the tests should have been updated.
Importantly, there are many known-bug tests linking to #110395. This *probably* isn't right - that is a tracking issue. But I don't really know what the "right" thing to do here. Probably, most that are actually *supposed* to be tests for const trait need to be linked to *that* tracking issue. And any other tests that were mislabeled need to be handled accordingly e.g. #130482. cc `@fee1-dead`
Fix error span if arg to `asm!()` is a macro call
Fixes#129503
When the argument to `asm!()` is a macro call, e.g. `asm!(concat!("abc", "{} pqr"))`, and there's an error in the resulting template string, we do not take into account the presence of this macro call while computing the error span. This PR fixes that. Now we will use the entire thing between the parenthesis of `asm!()` as the error span in this situation e.g. for `asm!(concat!("abc", "{} pqr"))` the error span will be `concat!("abc", "{} pqr")`.
Use `&raw` in the compiler
Like #130865 did for the standard library, we can use `&raw` in the
compiler now that stage0 supports it. Also like the other issue, I did
not make any doc or test changes at this time.
Move Apple linker args from `rustc_target` to `rustc_codegen_ssa`
They are dependent on the deployment target and SDK version, but having these in `rustc_target` makes it hard to introduce that dependency. Part of the work needed to do https://github.com/rust-lang/rust/issues/118204, see https://github.com/rust-lang/rust/pull/129342 for some discussion.
Tested using:
```console
./x test tests/run-make/apple-deployment-target --target="aarch64-apple-darwin,aarch64-apple-ios,aarch64-apple-ios-macabi,aarch64-apple-ios-sim,aarch64-apple-tvos,aarch64-apple-tvos-sim,aarch64-apple-visionos,aarch64-apple-visionos-sim,aarch64-apple-watchos,aarch64-apple-watchos-sim,arm64_32-apple-watchos,armv7k-apple-watchos,armv7s-apple-ios,x86_64-apple-darwin,x86_64-apple-ios,x86_64-apple-ios-macabi,x86_64-apple-tvos,x86_64-apple-watchos-sim,x86_64h-apple-darwin"
IPHONEOS_DEPLOYMENT_TARGET=10.0 ./x test tests/run-make/apple-deployment-target --target=i386-apple-ios
```
`arm64e-apple-darwin` and `arm64e-apple-ios` have not been tested, see https://github.com/rust-lang/rust/issues/130085, neither is `i686-apple-darwin`, since that requires using an x86_64 macbook, and I currently can't get mine to work, see https://github.com/rust-lang/rust/issues/130434.

rustdoc perf: clone `clean::Item` less
In https://github.com/rust-lang/rust/pull/130798, I caused a small perf regression for rustdoc (see https://github.com/rust-lang/rust/pull/130807#issuecomment-2373116917), so here is a small improvement to make up for it 😺.
This change is actually unrelated to the minor perf regression in `Item::stability` and instead fixes a more relevant perf problem that I found while investigating: For certain crates with many impls on type aliases, we unnecessarily cloned large `clean::Item`s multiple times -- now we just borrow them.

Partially update `library/Cargo.lock`
Run `cargo update` in library but exclude updates to `cc` and to `compiler_builtins`. Exclusions were done because `cc` seems to have some issues updating [1], and `compiler_builtins` needs to be updated on its own.
Partially supersedes https://github.com/rust-lang/rust/pull/129538.

Revert Break into the debugger on panic (129019)
This was talked about a bit at a recent libs meeting. While I think experimenting with this is worthwhile, I am nervous about this new behaviour reaching stable. We've already reverted on one tier 1 platform (Linux, https://github.com/rust-lang/rust/pull/130810) which means we have differing semantics on different tier 1 platforms. Also the fact it triggers even when `catch_unwind` is used to catch the panic means it can be very noisy in some projects.
At the very least I think it could use some more discussion before being instantly stable. I think this could maybe be re-landed with an environment variable to control/override the behaviour. But that part would likely need a libs-api decision.

[rustdoc] Remove unneeded jinja comments
This is a follow-up of https://github.com/rust-lang/rust/pull/130585.
Since we now check for the jinja comments we missed, we can now check for the jinja comments which are unneeded. It will make the parsing and therefore the compilation a tiny bit faster (well, if anyone sees a difference haha). The real goal is mostly to have easier to read template files. 😉
r? ``@notriddle``
[`cfg_match`] Generalize inputs
cc #115585
Changes the input type from `item` to `tt`, which makes the macro have the same functionality of `cfg_if`.
Also adds a test to ensure that `stmt_expr_attributes` is not triggered.
When the template string passed to asm!() is produced by
a macro call like concat!() we were producing wrong error
spans. Now in the case of a macro call we just use the entire
arg to asm!(), macro call and all, as the error span.
Like #130865 did for the standard library, we can use `&raw` in the
compiler now that stage0 supports it. Also like the other issue, I did
not make any doc or test changes at this time.
