Tomasz Miąsko ecd7862dfb Recognize discriminant reads as no-ops in RemoveNoopLandingPads
The cleanup blocks often contain read of discriminants. Teach
RemoveNoopLandingPads to recognize them as no-ops to remove
additional no-op landing pads.

rustc_target: Refactor away `TargetResult`

Follow-up to https://github.com/rust-lang/rust/pull/77202.

Construction of a built-in target is always infallible now, so `TargetResult` is no longer necessary.

The second commit contains some further cleanup based on built-in target construction being infallible.

Always use the Rust version in package names

The format of the tarballs produced by CI is roughly the following:

    {component}-{release}-{target}.{ext}

While on the beta and nightly channels `{release}` is just the channel name, on the stable channel is either the Rust version or the version of the component we're shipping:

    cargo-0.47.0-x86_64-unknown-linux-gnu.tar.xz
    clippy-0.0.212-x86_64-unknown-linux-gnu.tar.xz
    llvm-tools-1.46.0-x86_64-unknown-linux-gnu.tar.xz
    miri-0.1.0-x86_64-unknown-linux-gnu.tar.xz
    rls-1.41.0-x86_64-unknown-linux-gnu.tar.xz
    rust-1.46.0-x86_64-unknown-linux-gnu.tar.xz
    ...

This makes it really hard to get the package URL without having access to the manifest (and there is no manifest on ci-artifacts.rlo), as there is no consistent version number to use.

This PR addresses the problem by always using the Rust version number as `{release}` for the stable channel, regardless of the version number of the component we're shipping. I chose that instead of "stable" to avoid breaking the URL scheme *that* much.

Rustup should not be affected by this change, as it fetches the URLs from the manifest. Unfortunately we don't have a way to test other clients before making a stable release, as this change only affects the stable channel.

unix/vxworks: make DirEntry slightly smaller

`DirEntry` contains a `ReadDir` handle, which used to just be a wrapper
on `Arc<InnerReadDir>`. Commit af75314ecd added `end_of_stream: bool`
which is not needed by `DirEntry`, but adds 8 bytes after padding. We
can let `DirEntry` have an `Arc<InnerReadDir>` directly to avoid that.

Resolve intra-doc links on additional documentation for re-exports in lexical scope

Fixes https://github.com/rust-lang/rust/issues/77254.

- Preserve the parent module of `DocFragment`s
  + Add `parent_module` to `DocFragment`
  + Require the `parent_module` of the item being inlined
  + Preserve the hir_id for ExternCrates so rustdoc can find the parent module later
  + Take an optional `parent_module` for `build_impl` and `merge_attrs`.
    Preserve the difference between parent modules for each doc-comment.
  + Support a single additional re-exports in from_ast. Originally this took a vec but I ended up not using it.
  + Don't require the parent_module for all `impl`s, just inlined items

    In particular, this will be `None` whenever the attribute is not on a
    re-export.

  + Only store the parent_module, not the HirId

    When re-exporting a re-export, the HirId is not available. Fortunately,
    `collect_intra_doc_links` doesn't actually need all the info from a
    HirId, just the parent module.

- Introduce `Divider`

  This distinguishes between documentation on the original from docs on  the re-export.

- Use the new module information for intra-doc links

  + Make the parent module conditional on whether the docs are on a re-export
  + Make `resolve_link` take `&Item` instead of `&mut Item`

    Previously the borrow checker gave an error about multiple mutable
    borrows, because `dox` borrowed from `item`.

  + Fix `crate::` for re-exports

    `crate` means something different depending on where the attribute
    came from.

  + Make it work for `#[doc]` attributes too

    This required combining several attributes as one so they would keep
    the links.

clippy_lints: Do not warn against Box parameter in C FFI

changelog: [`boxed_local`]: don't lint in `extern fn` arguments

Fixes #5542.

When using C FFI, to handle pointers in parameters it is needed to
declare them as `Box` in its Rust-side signature. However, the current
linter warns against the usage of Box stating that "local variable
doesn't need to be boxed here".

This commit fixes it by ignoring functions whose Abi is C.

bors 265e4841b7 Auto merge of #6117 - dtolnay:string_lit_as_bytes, r=ebroto
Downgrade string_lit_as_bytes to nursery

Between #1402 (regarding `to_owned`) and #4494 (regarding `impl Read`), as well as other confusion I've seen hit in my work codebase involving string_lit_as_bytes (`"...".as_bytes().into()`), I don't think this lint is at a quality to be enabled by default.

I would consider re-enabling this lint after it is updated to understand when the surrounding type information is sufficient to unsize `b"..."` to &\[u8\] without causing a type error.

As currently implemented, this lint is pushing people to write `&b"_"[..]` which is not an improvement over `"_".as_bytes()` as far as I am concerned.

Add compile fail test for issue 27675

A recently merged PR (#73905) strengthened the checks on bounds of associated items. This rejects the attack path of #27675 which consisted of constructing a `dyn Trait<Item=T>` where `T` would not fulfill the bounds required on `Item` of the `Trait` behind the dyn object.

This regression test, extracted from [the weaponized instance](https://github.com/rust-lang/rust/issues/27675#issuecomment-696956878), checks that this is rejected.

(docs): make mutex error comment consistent with codebase

Although exceptionally minor, I found this stands out from other error reporting language used in doc comments. With the existence of the `failure` crate, I suppose this could be slightly ambiguous.

BTreeMap: comment why drain_filter's size_hint is somewhat pessimistic

The `size_hint` of the `DrainFilter` iterator doesn't adjust as you iterate. This hardly seems important to me, but there has been a comparable PR #64383 in the past. I guess a scenario is that you first iterate half the map manually and keep most of the key/value pairs in the map, and then tell the predicate to drain most of the key/value pairs and `.collect` the iterator over the remaining half of the map.

I am totally ambivalent whether this is better or not.
