Document subtleties of `ManuallyDrop`

After seeing rust-lang#130140 and rust-lang#130141, I figured that `ManuallyDrop` needs documentation explaining its subtleties, hence this PR.

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}");
        }
    }
}
```

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.

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.

Use `mem::offset_of!` for `sockaddr_un.sun_path`

We don't need manual pointer math here anymore!

rustdoc: do not animate :target when user prefers reduced motion

This accessibility improvement gates rust-lang#129284 behind an inverted [prefers-reduced-motion](https://developer.mozilla.org/en-US/docs/Web/CSS/`@media/prefers-reduced-motion)` media query.

Update FIXME comment in s390x_unknown_linux_*.rs

- Remove comment about "LLVM < 16" since the minimum external LLVM version is 16+ since rust-lang#117947
- Reflect rename of cabi_s390x.rs in rust-lang@030244c (renamed to [abi/call/s390x.rs](rust-lang@030244c#diff-20136d4a18fa0ef9bd4fc2e6f92e88daad6be88bfb156e5702af39ee87ca4879), and it is currently [still in the same location](https://github.com/rust-lang/rust/blob/9e394f551c050ff03c6fc57f190e0761cf0be6e8/compiler/rustc_target/src/abi/call/s390x.rs)).
