Move `doc(primitive)` future incompat warning to `invalid_doc_attributes`
Fixes#88070.
It's been a while since this was turned into a "future incompatible lint" so I think we can now turn it into a hard error without problem.

Initial support for return type notation (RTN)
See: https://smallcultfollowing.com/babysteps/blog/2023/02/13/return-type-notation-send-bounds-part-2/
1. Only supports `T: Trait<method(): Send>` style bounds, not `<T as Trait>::method(): Send`. Checking validity and injecting an implicit binder for all of the late-bound method generics is harder to do for the latter.
* I'd add this in a follow-up.
3. ~Doesn't support RTN in general type position, i.e. no `let x: <T as Trait>::method() = ...`~
* I don't think we actually want this.
5. Doesn't add syntax for "eliding" the function args -- i.e. for now, we write `method(): Send` instead of `method(..): Send`.
* May be a hazard if we try to add it in the future. I'll probably add it in a follow-up later, with a structured suggestion to change `method()` to `method(..)` once we add it.
7. ~I'm not in love with the feature gate name 😺~
* I renamed it to `return_type_notation` ✔️
Follow-up PRs will probably add support for `where T::method(): Send` bounds. I'm not sure if we ever want to support return-type-notation in arbitrary type positions. I may also make the bounds require `..` in the args list later.

Remove the `NodeId` of `ast::ExprKind::Async`
This is a followup to https://github.com/rust-lang/rust/pull/104833#pullrequestreview-1314537416.
In my original attempt, I was using `LoweringContext::expr`, which was not correct as it creates a fresh `DefId`.
It now uses the correct `DefId` for the wrapping `Expr`, and also makes forwarding `#[track_caller]` attributes more explicit.
resolve: Rename some cstore methods to match queries and add comments
about costs associated with replacing them with query calls.

Move useless_anynous_reexport lint into unused_imports
As mentioned in https://github.com/rust-lang/rust/pull/109003, this check should have been merged with `unused_imports` in the start.

Lint ambiguous glob re-exports
Attempts to fix#107563.
We currently already emit errors for ambiguous re-exports when two names are re-exported *specifically*, i.e. not from glob exports. This PR attempts to emit deny-by-default lints for ambiguous glob re-exports.
rustc_interface: Add a new query `pre_configure`
It partially expands crate attributes before the main expansion pass (without modifying the crate), and the produced preliminary crate attribute list is used for querying a few attributes that are required very early.
Crate-level cfg attributes on the crate itself are then expanded normally during the main expansion pass, like attributes on any other nodes.
This is a continuation of https://github.com/rust-lang/rust/pull/92473 and one more step to very unstable crate-level proc macro attributes maybe actually working.
Previously crate attributes were pre-configured simultaneously with feature extraction, and then written directly into `ast::Crate`.

rustc: Remove unused `Session` argument from some attribute functions
(One auxiliary test file containing one of these functions was unused, so I removed it instead of updating.)
rustdoc: Cleanup parent module tracking for doc links
Keep ids of the documented items themselves, not their parent modules. Parent modules can be retreived from those ids when necessary.
Fixes https://github.com/rust-lang/rust/issues/108501.
That issue could be fixed in a more local way, but this refactoring is something that I wanted to do since https://github.com/rust-lang/rust/pull/93805 anyway.
resolve: Improve debug impls for `NameBinding`
Print at least the Some/None/Ok/Err status of the nested bindings if not the bindings themselves.
Noticed while reviewing https://github.com/rust-lang/rust/pull/108729.
Do not ICE for unexpected lifetime with ConstGeneric rib
Fixes#109143
r? ````@petrochenkov````
Combining this test with the previous test will affect the previous diagnostics, so I added a separate test case.
This makes it easier to open the messages file while developing on features.
