I would like to rename it to `Type::Path`, but then it can't be
re-exported since the name would conflict with the `Path` struct.
Usually enum variants are referred to using their qualified names in
Rust (and parts of rustdoc already do that with `clean::Type`), so this
is also more consistent with the language.
* Do not emit unnecessary E0308 after E0070
* Show fewer errors on `while let` missing `let`
* Hide redundant E0308 on `while let` missing `let`
* Point at binding definition when possible on invalid assignment
* do not point at closure twice
* do not suggest `if let` for literals in lhs
* account for parameter types
Do not visit attributes in `ItemLowerer`.
By default, AST visitors visit expressions that appear in key-value attributes.
Those expressions should not be lowered to HIR, as they do not correspond to actually compiled code.
Since an attribute cannot produce meaningful HIR, just skip them altogether.

Print associated types on opaque `impl Trait` types
This PR generalizes #91021, printing associated types for all opaque `impl Trait` types instead of just special-casing for future.
before:
```
error[E0271]: type mismatch resolving `<impl Iterator as Iterator>::Item == u32`
```
after:
```
error[E0271]: type mismatch resolving `<impl Iterator<Item = usize> as Iterator>::Item == u32`
```

Questions:
1. I'm kinda lost in binders hell with this one. Is all of the `rebind`ing necessary?
2. Is there a map collection type that will give me a stable iteration order? Doesn't seem like TraitRef is Ord, so I can't just sort later..
3. I removed the logic that suppresses printing generator projection types. It creates outputs like this [gist](https://gist.github.com/compiler-errors/d6f12fb30079feb1ad1d5f1ab39a3a8d). Should I put that back?
4. I also added spaces between traits, `impl A+B` -> `impl A + B`. I quite like this change, but is there a good reason to keep it like that?

Link with default MACOSX_DEPLOYMENT_TARGET if not otherwise specified.
This PR sets the MACOSX_DEPLOYMENT_TARGET environment variable during the linking stage to our default, if it is not specified. This way it matches the deployment target we pass to llvm. If not set the the linker uses Xcode or Xcode commandline tools default which varies by version.
Fixes#90342, #91082.
Drive-by fixes to make Rust behave more like clang:
* Default to 11.0 deployment target for ARM64 which is the earliest version that had support for it.
* Set the llvm target to `arm64-apple-macosx<deployment target>` instead of `aarch64-apple-macosx<deployment target>`.
Various fixes for const_trait_impl
A few problems I found while making `Iterator` easier to const-implement.
1. More generous `~const Drop` check.
We check for nested fields with caller bounds.
For example, an ADT type with fields of types `A`, `B`, `C`, check if all of them are either:
- Bounded (`A: ~const Drop`, `B: Copy`)
- Known to be able to destruct at compile time (`C = i32`, `struct C(i32)`, `C = some_fn`)
2. Don't treat trait functions marked with `#[default_method_body_is_const]` as stable const fns when checking `const_for` and `const_try` feature gates.
I think anyone can review this, so no r? this time.
rustdoc: Remove `ResolvedPath.did`
`ResolvedPath.did` was not actually the same as `.path.def_id()`. Instead,
`.did` referred to the `DefId` of the page to be used as a hyperlink target.
For example, a link to `Struct::method()` would use `Struct`'s `DefId` as its
`.did` field. This behavior is confusing, easy to accidentally misuse, and can
instead be obtained on-demand when computing hyperlink targets. It's also likely
part of the reason `kind_side_channel` exists. I'm currently working on some
experimental refactorings in `collect_intra_doc_links` that I believe require --
or at least benefit from -- removing `.did`.

Tokenize emoji as if they were valid identifiers
In the lexer, consider emojis to be valid identifiers and reject
them later to avoid knock down parse errors.
Partially address #86102.
We had been injecting the list of themes and the rustdoc version into
main.js by rewriting it at doc generation time. By avoiding this
rewrite, we can make it easier to edit main.js without regenerating all
the docs.
Added a more convenient accessor for rustdoc-vars.
Changed storage.js to not rely on resourcesSuffix. It could in theory
use rustdoc-vars, but because rustdoc-vars is at the end of the HTML,
it's not available when storage.js runs (very early in page load).
We carry around a list of stylesheets that can carry two different types
of thing:
1. Internal stylesheets specific to a page type (only for settings)
2. Themes
In this change I move the link generation for settings.css into
settings(), so Context.style_files is reserved just for themes.
We had two places where we extracted a base theme name from a list of
StylePaths. I consolidated that code to be a method on StylePath.
I moved generation of link tags for stylesheets into the page.html
template. With that change, I made the template responsible for special
handling of light.css (making it the default theme) and of the other
themes (marking them disabled). That allowed getting rid of the
`disabled` field on StylePath.
rustdoc: Add test for mixing doc comments and attrs
This is a step toward adding more test coverage to make it easier to
remove the distinction between collapsed and uncollapsed doc values.
Restrict aarch64 outline atomics to glibc for now.
The introduced dependency on `getauxval` causes linking problems with musl, making compiling any binaries for `aarch64-unknown-linux-musl` impossible without workarounds such as using lld or adding liblibc.rlib again to the linker invocation, see #89626.
This is a workaround until libc>0.2.108 is merged.
Partially stabilize `duration_consts_2`
Methods that were only blocked on `const_panic` have been stabilized.
The remaining methods of `duration_consts_2` are all related to floats,
and as such have been placed behind the `duration_consts_float` feature
gate.
