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.
On implicit `Sized` bound on fn argument, point at type instead of pattern

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.

update `compiler-builtins` to 0.1.126
this requires the addition of a bootstrap variant of the new `naked_asm!` macro

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.

rustdoc: do not animate :target when user prefers reduced motion
This accessibility improvement gates #129284 behind an inverted [prefers-reduced-motion](https://developer.mozilla.org/en-US/docs/Web/CSS/`@media/prefers-reduced-motion)` media query.
Pass Module Analysis Manager to Standard Instrumentations
This PR introduces changes related to llvm::PassInstrumentationCallbacks. Now, we pass Module Analysis Manager to StandardInstrumentations::registerCallbacks, so it can take advantage of such instrumentations as IR verifier or preserved CFG checker. So basically this is NFC PR.
Utf8Chunks: add link to Utf8Chunk
It is currently surprisingly non-trivial to go from the `utf8_chunks` method to the docs of the `valid`/`invalid` methods used in the example. This should help.
Fix diagnostics for coroutines with () as input.
This may be a more real-life example to trigger the diagnostic:
```rust
#![features(try_blocks, coroutine_trait, coroutines)]
use std::ops::Coroutine;
struct Request;
struct Response;
fn get_args() -> Result<String, String> { todo!() }
fn build_request(_arg: String) -> Request { todo!() }
fn work() -> impl Coroutine<Option<Response>, Yield = Request> {
#[coroutine]
|_| {
let r: Result<(), String> = try {
let req = get_args()?;
yield build_request(req)
};
if let Err(msg) = r {
eprintln!("Error: {msg}");
}
}
}
```
