Don't use serde-derive in the rls shim
The already-small RLS shim can get a little smaller, and faster to
build, if we drop the serde-derive dependency and decode the one
"method" field it needs manually from `serde_json::Value`.
Remove `rustc_llvm` from llvm-stamp nags
LLVM is not *built* by `compiler/rustc_llvm` at all, only bindings on
top of it, so there's no need to bump `download-ci-llvm-stamp` for that.
Dynamically size sigaltstk in rustc
rustc installs a signal stack that assumes that MINSIGSTKSZ is a constant, unchanging value. Newer hardware undermines that assumption greatly, with register files larger than glibc's traditional static MINSIGSTKZ. Properly handle this so that it is correct on all supported Linux versions with all CPUs.
style-guide: Expand example of combinable expressions to include arrays
Arrays are allowed as combinable expressions, but none of the examples
show that.
CI: use `macos-13` runner for Apple jobs
Trying if performance of Apple CI improves with macOS 13 and SIP disabled. Speed-up:
```
x86_64-apple-1: ~2h 20m > ~1h 20m
x86_64-apple-2: ~1h 45m > ~1h 15m
```

This setting was added to match rustfmt, but it's been taking effect on
all file editing, which I notice most on git `COMMIT_EDITMSG`. I want to
keep my default 72-width commit messages, please. :)

Replace RPITIT current impl with new strategy that lowers as a GAT
This PR replaces the current implementation of RPITITs with the new implementation that we had under -Zlower-impl-trait-in-trait-to-assoc-ty flag that lowers the RPIT as a GAT on the trait and on the impls that implement that trait.
Opening this PR as a draft because this goes after #112682, ~#112981~ and ~#112983~.
As soon as those are merged, I can rebase and we should run perf, crater and test a lot.
r? `@compiler-errors`
Add `Read`, `Write` and `Seek` impls for `Arc<File>` where appropriate
If `&T` implements these traits, `Arc<T>` has no reason not to do so
either. This is useful for operating system handles like `File` or
`TcpStream` which don't need a mutable reference to implement these
traits.

Add filter with following segment while lookup typo for path
From the discussion: https://github.com/rust-lang/rust/pull/112917#discussion_r1239150173
Seems we can not get the assoc items for `Struct`, `Enum` in the resolving phase.
A obvious filter is avoid suggesting the same name with the following segment path.
Use `following_seg` can extend the function `smart_resolve_partial_mod_path_errors` for more scenarios, such as `std::sync_error::atomic::AtomicBool` in test case.

move pal cfgs in f32 and f64 to sys
I'd like to push forward on `sys` being a separate crate. To start with, most of these PAL exception cases are very simple little bits of code like this, so I thought I would try tidying them up.
