Remove me from libcore review rotation

I'm looking at my commitments right now, and unfortunately this needs to go for at least a while.

If there's something in particular I can probably still take them, but I should drop out of the rotation for now.

Rollup merge of #116732 - onur-ozkan:resolve-linked-x, r=Mark-Simulacrum
Make x capable of resolving symlinks

When bootstrapping from outside of the rust source, instead of calling 'x' from the absolute path
(like /home/user/rust/x), we should be able to link 'x' from the rust source to binary paths so it can be used easily. Before this change, 'x' was not capable of finding 'x.py' when called from the linked file.

Rollup merge of #116522 - bvanjoi:fix-115599, r=oli-obk
use `PatKind::Error` when an ADT const value has violation

Fixes #115599

Since the [to_pat](https://github.com/rust-lang/rust/pull/111913/files#diff-6d8d99538aca600d633270051580c7a9e40b35824ea2863d9dda2c85a733b5d9R126-R155) behavior has been changed in the #111913 update, the kind of `inlined_const_ast_pat` has transformed from `PatKind::Leaf { pattern: Pat { kind: Wild, ..} } ` to `PatKind::Constant`. This caused a scenario where there are no matched candidates, leading to a testing of the candidates. This process ultimately attempts to test the string const, triggering the `bug!` invocation finally.

Rollup merge of #116172 - joboet:recursive_tls_initialization, r=dtolnay
Broaden the consequences of recursive TLS initialization

This PR updates the documentation of `LocalKey` to clearly disallow the behaviour described in [this comment](https://github.com/rust-lang/rust/issues/110897#issuecomment-1525738849). This allows using `OnceCell` for the lazy initialization of TLS variables, which panics on reentrant initialization instead of updating the value like TLS variables currently do.

64368d0279 Auto merge of #110729 - ColinFinck:decode-utf16-fused-iterator, r=dtolnay
Implement FusedIterator for DecodeUtf16 when the inner iterator does

I have just implemented an iterator that wraps `DecodeUtf16` and wanted to implement `FusedIterator` for my iterator when I noticed that `DecodeUtf16` currently doesn't implement `FusedIterator` at all.
A quick look at the code of `DecodeUtf16` revealed that `DecodeUtf16::next` only returns `None` when its inner iterator returns `None`:
3462f79e94/library/core/src/char/decode.rs (L45)

As a result, we can implement `FusedIterator` for `DecodeUtf16` when the inner iterator does.

I'm following the example of #96397 here and consider this change minor and non-controversial, which is why I haven't added an RFC. I have also added the required feature name (`"decode_utf16_fused_iterator"`), however without adding a chapter to the Rust Unstable book (same as #96397).

Format all the let-chains in compiler crates

Since rust-lang/rustfmt#5910 has landed, soon we will have support for formatting let-chains (as soon as rustfmt syncs and beta gets bumped).

This PR applies the changes [from master rustfmt to rust-lang/rust eagerly](https://rust-lang.zulipchat.com/#narrow/stream/122651-general/topic/out.20formatting.20of.20prs/near/374997516), so that the next beta bump does not have to deal with a 200+ file diff and can remain concerned with other things like `cfg(bootstrap)` -- #113637 was a pain to land, for example, because of let-else.

I will also add this commit to the ignore list after it has landed.

The commands that were run -- I'm not great at bash-foo, but this applies rustfmt to every compiler crate, and then reverts the two crates that should probably be formatted out-of-tree.
```
~/rustfmt $ ls -1d ~/rust/compiler/* | xargs -I@ cargo run --bin rustfmt -- `@/src/lib.rs` --config-path ~/rust --edition=2021 # format all of the compiler crates
~/rust $ git checkout HEAD -- compiler/rustc_codegen_{gcc,cranelift} # revert changes to cg-gcc and cg-clif
```

cc `@rust-lang/rustfmt`
r? `@WaffleLapkin` or `@Nilstrieb` who said they may be able to review this purely mechanical PR :>

cc `@Mark-Simulacrum` and `@petrochenkov,` who had some thoughts on the order of operations with big formatting changes in https://github.com/rust-lang/rust/pull/95262#issue-1178993801. I think the situation has changed since then, given that let-chains support exists on master rustfmt now, and I'm fairly confident that this formatting PR should land even if *bootstrap* rustfmt doesn't yet format let-chains in order to lessen the burden of the next beta bump.

6ab84b5895 Fix podman detection in CI scripts
When docker-podman compat was set up in a way that causes "docker"
to be the argv[0] of podman, the previous detection did not work.
This was for example the case in the compat package from nixpkgs.

This checks the output and should work everywhere.

Fix `std::convert::TryFrom` doc

Original text:

> truncating the [i64](https://doc.rust-lang.org/std/primitive.i64.html) to an [i32](https://doc.rust-lang.org/std/primitive.i32.html) (essentially giving the [i64](https://doc.rust-lang.org/std/primitive.i64.html)’s value modulo [i32::MAX](https://doc.rust-lang.org/std/primitive.i32.html#associatedconstant.MAX))

This can't be true, because `i32::MAX` is an odd number. The correct value seems `(i32::MAX + 1) * 2`, but this is complicated and distracting, and I suggest removing the parentheses entirely.

ff5664d600 Auto merge of #116683 - ChrisDenton:exists, r=Mark-Simulacrum
Make `try_exists` return `Ok(true)` for Windows Unix Sockets

This is a follow up to #109106 but for[ `fs::try_exists`](https://doc.rust-lang.org/std/fs/fn.try_exists.html), which doesn't need to get the metadata of a file (which can fail even if a file exists).

`fs::try_exists` currently fails on Windows if encountering a Unix Domain Socket (UDS). This PR fixes it by checking for an error code that's returned when there's a failure to use a reparse point.

## Reparse points

A reparse point is a way to invoke a filesystem filter on a file instead of the file being opened normally. This is used to implement symbolic links (by redirecting to a different path) but also to implement other types of special files such as Unix domain sockets. If the reparse point is not a link type then opening it with `CreateFileW` may fail with `ERROR_CANT_ACCESS_FILE` because the filesystem filter does not implement that operation. This differs from resolving links which may fail with errors such as `ERROR_FILE_NOT_FOUND` or `ERROR_CANT_RESOLVE_FILENAME`.

So `ERROR_CANT_ACCESS_FILE` means that the file exists but that we can't open it normally. Still, the file does exist on the filesystem so `try_exists` should report that as `Ok(true)`.
