…tAddr`

`(x: SocketAddr).into_inner()` evaluates to `(SocketAddrCRepr,
socklen_t)` instead of `(*const sockaddr, socklen_t)` as of
commit 55e23db.

This brings the `--crate-type`,  `--emit`, and `--print` options' allowed arguments into sync with that printed by `rustc --help`.

`codegen_fulfill_obligation` expect erased regions

it's a query, so by erasing regions before calling it, we get better caching.
This doesn't actually change anything as its already the status quo.

only run --all-targets in stage0 for Std

Repro'd the issue with `python3 x.py check --stage 1 library/std` and tested the fix with the same command.

r? `@jyn514`

I tried to implement [this solution](rust-lang#98720 (comment)), but didn't have any luck. I don't think I fully understood what needed to be done. However, I would love to be mentored on it since it would be a more correct solution, and I can learn more about how bootstrap works.

…d-height, r=notriddle

Fix item info pos and height

Fixes rust-lang#98266.
Fixes rust-lang#98343.

You can test it [here](https://rustdoc.crud.net/imperio/fix-item-info-pos-and-height/lib2/trait.Trait.html).

Here is a screenshot of the result:

…ee1-dead

Remove `guess_head_span`

follow-up to rust-lang#98519

…ion, r=fee1-dead

Use Parser's `restrictions` instead of `let_expr_allowed`

This also means that the `ALLOW_LET` flag is reset properly for subexpressions, so we can properly deny things like `a && (b && let c = d)`. Also the parser is a tiny bit smaller now.

It doesn't reject _all_ bad `let` expr usages, just a bit more.

kmc-solid: Update `Socket::connect_timeout` to be in line with rust-lang#78802

Fixes the build failure of the [`*-kmc-solid_*`](https://doc.rust-lang.org/nightly/rustc/platform-support/kmc-solid.html) Tier 3 targets after rust-lang#78802.

```

Update rustc man page to match `rustc --help`

This brings the `--crate-type`,  `--emit`, and `--print` options' allowed arguments into sync with that printed by `rustc --help`.

c.f. the `opt::multi_s` calls for `"crate-type"`, `"emit"`, and `"print"` here: https://github.com/rust-lang/rust/blob/master/compiler/rustc_session/src/config.rs
