Although `manual_inspect`'s PR started some months ago, the lint is only
available in the current nightly (1.81.0), rather than 1.78.0.

Implement new effects desugaring
cc `@rust-lang/project-const-traits.` Will write down notes once I have finished.
* [x] See if we want `T: Tr` to desugar into `T: Tr, T::Effects: Compat<true>`
* [x] Fix ICEs on `type Assoc: ~const Tr` and `type Assoc<T: ~const Tr>`
* [ ] add types and traits to minicore test
* [ ] update rustc-dev-guide

Rename `super_predicates_of` and similar queries to `explicit_*` to note that they're not elaborated
Rename:
* `super_predicates_of` -> `explicit_super_predicates_of`
* `implied_predicates_of` -> `explicit_implied_predicates_of`
* `supertraits_containing_assoc_item` -> `explicit_supertraits_containing_assoc_item`
This makes it clearer that, unlike (for example) [`TyCtxt::super_traits_of`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/context/struct.TyCtxt.html#method.super_traits_of), we don't automatically elaborate this set of predicates.

doc_lazy_continuation: blank comment line for gap
This change addresses cases where doc comments are separated by blank lines, comments, or non-doc-comment attributes, like this:
```rust
/// - first line
// not part of doc comment
/// second line
```
Before this commit, Clippy gave a pedantically-correct warning about how you needed to indent the second line. This is unlikely to be what the user intends, and has been described as a "false positive." Since Clippy is warning you about a highly unintuitive behavior [that Rustdoc actually has](https://notriddle.com/rustdoc-html-demo-11/lazy-continuation-bad/test_dingus_2024/constant.D.html), we definitely want it to output *something*, but the suggestion to indent was poor.
Fixes#12917

Tighten `fn_decl_span` for async blocks
Tightens the span of `async {}` blocks in diagnostics, and subsequently async closures and async fns, by actually setting the `fn_decl_span` correctly. This is kinda a follow-up on #125078, but it fixes the problem in a more general way.
I think the diagnostics are significantly improved, since we no longer have a bunch of overlapping spans. I'll point out one caveat where I think the diagnostic may get a bit more confusing, but where I don't think it matters.

Fix doc_markdown DevOps false positive
This fixes an issue where the word "DevOps" ends up as a false positive for the `doc_markdown` lint.
In a doc comment like this
```rust
/// Call the Azure DevOps REST API.
pub fn example() {}
```
the word "DevOps" is highlighted as something which should be in backticks.
```
warning: item in documentation is missing backticks
--> src/lib.rs:1:20

This could be overriden with the `doc-valid-idents` configuration parameter as noted by the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#/doc_markdown), but I believe the word "DevOps" is sufficiently common to belong alongside exceptions like "GitHub" and "GitLab".

Eliminate the distinction between PREC_POSTFIX and PREC_PAREN precedence level
I have been tangling with precedence as part of porting some pretty-printer improvements from syn back to rustc (related to parenthesization of closures, returns, and breaks by the AST pretty-printer).
As far as I have been able to tell, there is no difference between the 2 different precedence levels that rustc identifies as `PREC_POSTFIX` (field access, square bracket index, question mark, method call) and `PREC_PAREN` (loops, if, paths, literals).
There are a bunch of places that look at either `prec < PREC_POSTFIX` or `prec >= PREC_POSTFIX`. But there is nothing that needs to distinguish PREC_POSTFIX and PREC_PAREN from one another.

In the interest of eliminating a distinction without a difference, this PR collapses these 2 levels down to 1.
There is exactly 1 case where an expression with PREC_POSTFIX precedence needs to be parenthesized in a location that an expression with PREC_PAREN would not, and that's when the receiver of ExprKind::MethodCall is ExprKind::Field. `x.f()` means a different thing than `(x.f)()`. But this does not justify having separate precedence levels because this special case in the grammar is not governed by precedence. Field access does not have "lower precedence than" method call syntax — you can tell because if it did, then `x.f[0].f()` wouldn't be able to have its unparenthesized field access in the receiver of a method call. Because this Field/MethodCall special case is not governed by precedence, it already requires special handling and is not affected by eliminating the PREC_POSTFIX precedence level.

ast: Standardize visiting order for attributes and node IDs
This should only affect `macro_rules` scopes and order of diagnostics.
Also add a deprecation lint for `macro_rules` called outside of their scope, like in https://github.com/rust-lang/rust/issues/124535.
Cache lintcheck binary in ci
Always trims ~40s off the `diff` job as it no longer needs to install the rust toolchain or compile lintcheck. Saves a further ~20s for the `base`/`head` jobs when the cache is warm
It now uses artifacts for restoring the JSON between jobs as per https://github.com/rust-lang/rust-clippy/pull/10398#discussion_r1642364392, cc `@flip1995`
The lintcheck changes are to make `./target/debug/lintcheck` work, running `cargo-clippy`/`clippy-driver` directly doesn't work without `LD_LIBRARY_PATH`/etc being set which is currently being done by `cargo run`. By merging the `--recursive` and normal cases to both go via regular `cargo check` we can have Cargo set up the environment for us

use short message format in integration test
While checking #12983, bors came upon a cargo change that put "E0463" into the standard error (as part of a test case code snippet), which the integration test picked up to fail the build. Talk about unforeseen consequences.
So this PR just changes the integration test to use short message format in order to not include the code snippets in the output. Hopefully that will fix the problem.

Fix `...` in multline code-skips in suggestions

For suggestions, we were "centering" the `...` with the line, but that was inconsistent with what we do in every other case *and* off-center.

If this not a "simple" pattern, better not emit the lint.
