1388b38c52 Auto merge of #95171 - Kobzol:llvm-ci-update, r=nikic
Update LLVM used for building rustc in CI for x64

LLVM 14 was tagged. It is needed for building [BOLT](https://github.com/rust-lang/rust/pull/94381), and it also improves max RSS quite [a lot](https://perf.rust-lang.org/compare.html?start=6970f88db3ac2a9cefa9c585228291ae1f18fb04&end=67acb7e3ffcc11d67abfd29c390aac629f3c0e97&stat=max-rss).

GCC was bumped to allow building the new LLVM version. The changes in building LLVM were done to speed up the build a bit by ignoring unused parts and to turn off parts that were problematic to compile even with the bumped GCC.

Implement Valtree to ConstValue conversion

Once we start to use `ValTree`s in the type system we will need to be able to convert them into `ConstValue` instances, which we want to continue to use after MIR construction.

3bfeffd55b Auto merge of #95904 - paolobarbolini:vecdeque-specextend, r=the8472
Add VecDeque::extend from vec::IntoIter and slice::Iter specializations

Inspired from the [`Vec` `SpecExtend` implementation](027a232755/library/alloc/src/vec/spec_extend.rs), but without the specialization for `TrustedLen` which I'll look into in the future.

Should help #95632 and https://github.com/KillingSpark/zstd-rs/pull/17

## Benchmarks

Before

```
test vec_deque::bench_extend_bytes    ... bench:         862 ns/iter (+/- 10)
test vec_deque::bench_extend_vec      ... bench:         883 ns/iter (+/- 19)
```

After

```
test vec_deque::bench_extend_bytes    ... bench:           8 ns/iter (+/- 0)
test vec_deque::bench_extend_vec      ... bench:          24 ns/iter (+/- 1)

0e7915d11f Auto merge of #96085 - jsgf:deny-unused-deps, r=compiler-errors
Make sure `-Dunused-crate-dependencies --json unused-externs` makes rustc exit with error status

This PR:
- fixes compiletest to understand unused extern notifications
- adds tests for `--json unused-externs`
- makes sure that deny-level unused externs notifications are treated as compile errors
  - refactors the `emit_unused_externs` callstack to plumb through the level as an enum as a string, and adds `Level::is_error`

Update: adds `--json unused-externs-silent` with the original behaviour since Cargo needs it. Should address `@est31's` concerns.

Rollup merge of #96483 - Urgau:check-cfg-target_feature, r=petrochenkov
Add missing `target_feature` to the list of well known cfg names

This PR adds the missing `target_feature` cfg name to the list of well known cfg names.

It was notice missing in https://github.com/rust-lang/rust/issues/96472 thanks to `@bjorn3,` the reason being that `--check-cfg=names()` automatically inherit the names passed by `--cfg` (or internal to `rustc`) and is seems that the vast majority of targets have at least one target feature leading to `target_feature` being a well known name in most target but it should always be a well known name so this PR add it unconditionally to list.

This PR fixes a few FIXME about not using `Option` in `dbg_scope` field of `DebugScope`, during `create_function_debug_context` func in codegen parts.

Rollup merge of #96421 - nnethercote:less-NoDelim, r=petrochenkov
Less `NoDelim`

Currently there are several places where `NoDelim` (which really means "implicit delimiter" or "invisible delimiter") is used to mean "no delimiter". The name `NoDelim` is a bit misleading, and may be a cause.

This PR changes these places, e.g. by changing a `DelimToken` to `Option<DelimToken>` and then using `None` to mean "no delimiter". As a result, the *only* place where `NoDelim` values are now produced is within:
- `Delimiter::to_internal()`, when converting from `Delimiter::None`.
- `FlattenNonterminals::process_token()`, when converting `TokenKind::Interpolated`.

Make EncodeWide implement FusedIterator

[`EncodeUtf16`](https://doc.rust-lang.org/std/str/struct.EncodeUtf16.html) and [`EncodeWide`](https://doc.rust-lang.org/std/os/windows/ffi/struct.EncodeWide.html) currently serve similar purposes: They convert from UTF-8 to UTF-16 and WTF-8 to WTF-16, respectively. `EncodeUtf16` wraps a &str, whereas `EncodeWide` wraps an &OsStr.

When Iteration has concluded, these iterators wrap an empty slice, which will forever yield `None` values. Hence, `EncodeUtf16` rightfully implements `FusedIterator`. However, `EncodeWide` in contrast does not, even though it serves an almost identical purpose.

This PR attempts to fix that issue. I consider this change minor and non-controversial, hence why I have not added a RFC/FCP. Please let me know if the stability attribute is wrong or contains a wrong version number. Thanks in advance.

make `fn() -> _ { .. }` suggestion MachineApplicable

This might not be valid, but it would be nice to promote this to `MachineApplicable` so people can use rustfix here.

Also de65fcf009d07019689cfad7f327667e390a325d is to [restore the suggestion for `issue-77179.rs`](de65fcf009 (diff-12e43fb5d6d12ec7cb5c6b48204a18d113cf5de0e12eb71a358b639bd9aadaf0R8)). (though in this case, the code in that issue still doesn't compile, so it's not marked with rustfix).

c95346b8ac Auto merge of #91557 - cjgillot:ast-lifetimes-named, r=petrochenkov
Perform lifetime resolution on the AST for lowering

Lifetime resolution is currently implemented several times. Once during lowering in order to introduce in-band lifetimes, and once in the resolve_lifetimes query. However, due to the global nature of lifetime resolution and how it interferes with hygiene, it is better suited on the AST.

This PR implements a first draft of lifetime resolution on the AST. For now, we specifically target named lifetimes and everything we need to remove lifetime resolution from lowering. Some diagnostics have already been ported, and sometimes made more precise using available hygiene information. Follow-up PRs will address in particular the resolution of anonymous lifetimes on the AST.

We reuse the rib design of the current resolution framework. Specific `LifetimeRib` and `LifetimeRibKind` types are introduced. The most important variant is `LifetimeRibKind::Generics`, which happens each time we encounter something which may introduce generic lifetime parameters. It can be an item or a `for<...>` binder. The `LifetimeBinderKind` specifies how this rib behaves with respect to in-band lifetimes.

07ea143f96 Revert "Re-export core::ffi types from std::ffi"
This reverts commit 9aed829fe6.

Fixes https://github.com/rust-lang/rust/issues/96435 , a regression
in crates doing `use std::ffi::*;` and `use std::os::raw::*;`.

We can re-add this re-export once the `core::ffi` types
are stable, and thus the `std::os::raw` types can become re-exports as
well, which will avoid the conflict. (Type aliases to the same type
still conflict, but re-exports of the same type don't.)
