After updating the minimum required LLVM version to 12 (#90175) we can use `apple-a14` as target CPU, because that CPU is similar in features to the Apple M1 (see [LLVM 13 source](https://github.com/llvm/llvm-project/blob/b8016b626ec7095c7d57ebfffb2135dc5c3077b8/llvm/lib/Target/AArch64/AArch64.td#L1127)).

Replace `std::os::raw::c_ssize_t` with `std::os::raw::c_ptrdiff_t`
The discussions in #88345 brought up that `ssize_t` is not actually the signed index type defined in stddef.h, but instead it's `ptrdiff_t`. It seems pretty clear that the use of `ssize_t` here was a mistake on my part, and that if we're going to bother having a isize-alike for FFI in `std::os::raw`, it should be `ptrdiff_t` and not `ssize_t`.
Anyway, both this and `c_size_t` are dubious in the face of the discussion in https://internals.rust-lang.org/t/pre-rfc-usize-is-not-size-t/15369, and any RFC/project-group/etc that handles those issues there should contend with these types in some manner, but that doesn't mean we shouldn't fix something wrong like this, even if it is unstable.
All that said, `size_t` is *vastly* more common in function signatures than either `ssize_t` or `ptrdiff_t`, so I'm going to update the tracking issue's list of unresolved questions to note that perhaps we only want `c_size_t` — I mostly added the signed version for symmetry, rather than to meet a need. (Given this, I'm also fine with modifying this patch to instead remove `c_ssize_t` without a replacement)

Update Clippy dependencies
Clippy has two outdated dependencies, where one indirect dependency has been flagged by rustsec for dropping a lifetime. See [RUSTSEC-2020-0146](https://rustsec.org/advisories/RUSTSEC-2020-0146). This PR updates these dependencies.
With previous dependency updates, it was tried to prevent duplicates in the `Cargo.lock` file of rust-lang/rust. I've tried to keep this in mind with this update.
* Dependency `semver`
* Used in `src/tools/cargo/Cargo.toml` as version `1.0.3`
* Used in `src/tools/rust-analyzer/crates/project_model/Cargo.toml` as version `1`
* Updated in Clippy from `0.11` to `1.0` (Clippy usually defines the major and minor patch version). The `Cargo.lock` file lists `1.0.3` which is one patch version behind the most recent one but prevents a duplicate with cargo's pinned version.
* Dependency `cargo_metadata`
* Used in several tools as `0.14`
* Used in `src/tools/tidy` and `src/tools/rls` as `0.12`
* Updated in Clippy from `0.12` to `0.14`
All updates to the `Cargo.lock` have been done automatically by `x.py`.
There are still some tools with these outdated dependencies. Clippy didn't require any changes, and it would be likely that the others could also be updated without any problem. Let me know if I should try to update them as well :upside_down_face:.

The usual way to check if a background thread is still running is to set some atomic flag at the end of its main function. We already do that, in the form of dropping an Arc which will reduce the reference counter. So we might as well expose that information.
This is useful in applications with a main loop (e.g. a game, gui, control system, ..) where you spawn some background task, and check every frame/iteration whether the background task is finished to .join() it in that frame/iteration while keeping the program responsive.

Add new tier 3 target: `x86_64-unknown-none`
Adds support for compiling OS kernels or other bare-metal applications for the x86-64 architecture.
Below are details on how this target meets the requirements for tier 3:
> A tier 3 target must have a designated developer or developers (the "target maintainers") on record to be CCed when issues arise regarding the target. (The mechanism to track and CC such developers may evolve over time.)
I would be willing to be a target maintainer, though I would appreciate if others volunteered to help with that as well.
> Targets must use naming consistent with any existing targets; for instance, a target for the same CPU or OS as an existing Rust target should use the same name for that CPU or OS. Targets should normally use the same names and naming conventions as used elsewhere in the broader ecosystem beyond Rust (such as in other toolchains), unless they have a very good reason to diverge. Changing the name of a target can be highly disruptive, especially once the target reaches a higher tier, so getting the name right is important even for a tier 3 target.
Uses the same naming as the LLVM target, and the same convention as many other bare-metal targets.
> Target names should not introduce undue confusion or ambiguity unless absolutely necessary to maintain ecosystem compatibility. For example, if the name of the target makes people extremely likely to form incorrect beliefs about what it targets, the name should be changed or augmented to disambiguate it.
I don't believe there is any ambiguity here.
> Tier 3 targets may have unusual requirements to build or use, but must not create legal issues or impose onerous legal terms for the Rust project or for Rust developers or users.
I don't see any legal issues here.
> The target must not introduce license incompatibilities.
> Anything added to the Rust repository must be under the standard Rust license (MIT OR Apache-2.0).
> The target must not cause the Rust tools or libraries built for any other host (even when supporting cross-compilation to the target) to depend on any new dependency less permissive than the Rust licensing policy. This applies whether the dependency is a Rust crate that would require adding new license exceptions (as specified by the tidy tool in the rust-lang/rust repository), or whether the dependency is a native library or binary. In other words, the introduction of the target must not cause a user installing or running a version of Rust or the Rust tools to be subject to any new license requirements.
>If the target supports building host tools (such as rustc or cargo), those host tools must not depend on proprietary (non-FOSS) libraries, other than ordinary runtime libraries supplied by the platform and commonly used by other binaries built for the target. For instance, rustc built for the target may depend on a common proprietary C runtime library or console output library, but must not depend on a proprietary code generation library or code optimization library. Rust's license permits such combinations, but the Rust project has no interest in maintaining such combinations within the scope of Rust itself, even at tier 3.
> Targets should not require proprietary (non-FOSS) components to link a functional binary or library.
> "onerous" here is an intentionally subjective term. At a minimum, "onerous" legal/licensing terms include but are not limited to: non-disclosure requirements, non-compete requirements, contributor license agreements (CLAs) or equivalent, "non-commercial"/"research-only"/etc terms, requirements conditional on the employer or employment of any particular Rust developers, revocable terms, any requirements that create liability for the Rust project or its developers or users, or any requirements that adversely affect the livelihood or prospects of the Rust project or its developers or users.
I see no issues with any of the above.
> Neither this policy nor any decisions made regarding targets shall create any binding agreement or estoppel by any party. If any member of an approving Rust team serves as one of the maintainers of a target, or has any legal or employment requirement (explicit or implicit) that might affect their decisions regarding a target, they must recuse themselves from any approval decisions regarding the target's tier status, though they may otherwise participate in discussions.
> This requirement does not prevent part or all of this policy from being cited in an explicit contract or work agreement (e.g. to implement or maintain support for a target). This requirement exists to ensure that a developer or team responsible for reviewing and approving a target does not face any legal threats or obligations that would prevent them from freely exercising their judgment in such approval, even if such judgment involves subjective matters or goes beyond the letter of these requirements.
Only relevant to those making approval decisions.
> Tier 3 targets should attempt to implement as much of the standard libraries as possible and appropriate (core for most targets, alloc for targets that can support dynamic memory allocation, std for targets with an operating system or equivalent layer of system-provided functionality), but may leave some code unimplemented (either unavailable or stubbed out as appropriate), whether because the target makes it impossible to implement or challenging to implement. The authors of pull requests are not obligated to avoid calling any portions of the standard library on the basis of a tier 3 target not implementing those portions.
`core` and `alloc` can be used. `std` cannot be used as this is a bare-metal target.
> The target must provide documentation for the Rust community explaining how to build for the target, using cross-compilation if possible. If the target supports running tests (even if they do not pass), the documentation must explain how to run tests for the target, using emulation if possible or dedicated hardware if necessary.
Use `--target=x86_64-unknown-none-elf` option to cross compile, just like any target. The target does not support running tests.
> Tier 3 targets must not impose burden on the authors of pull requests, or other developers in the community, to maintain the target. In particular, do not post comments (automated or manual) on a PR that derail or suggest a block on the PR based on a tier 3 target. Do not send automated messages or notifications (via any medium, including via `@)` to a PR author or others involved with a PR regarding a tier 3 target, unless they have opted into such messages.
> Backlinks such as those generated by the issue/PR tracker when linking to an issue or PR are not considered a violation of this policy, within reason. However, such messages (even on a separate repository) must not generate notifications to anyone involved with a PR who has not requested such notifications.
I don't foresee this being a problem.
> Patches adding or updating tier 3 targets must not break any existing tier 2 or tier 1 target, and must not knowingly break another tier 3 target without approval of either the compiler team or the maintainers of the other tier 3 target.
> In particular, this may come up when working on closely related targets, such as variations of the same architecture with different features. Avoid introducing unconditional uses of features that another variation of the target may not have; use conditional compilation or runtime detection, as appropriate, to let each target run code supported by that target.
No other targets should be affected by the pull request.

This changes `rustdoc` to recursively follow `Deref` targets so that methods from all levels are added to the rendered output. This implementation displays the methods from all levels in the expanded state with separate sections for each level.

rustdoc: Remove `Crate.src` and instead compute it on-demand
It is only used in one place; `src` was about a third of `Crate`'s total
size; `Crate` is frequently moved by-value; and `src` can be easily
computed on-demand.

Auto merge of #90205 - mati865:link-modifiers-in-rustc, r=petrochenkov
Repace use of `static_nobundle` with `native_link_modifiers` within Rust codebase
This fixes warnings when building Rust and running tests:
```
warning: library kind `static-nobundle` has been superseded by specifying `-bundle` on library kind `static`. Try `static:-bundle`
warning: `rustc_llvm` (lib) generated 2 warnings (1 duplicate)
```
