Port several trait/coherence-related attributes the new attribute system
Part of rust-lang/rust#131229
This ports:
- `#[const_trait]`
- `#[rustc_deny_explicit_impl]`
- `#[rustc_do_not_implement_via_object]`
- `#[rustc_coinductive]`
- `#[type_const]`
- `#[rustc_specialization_trait]`
- `#[rustc_unsafe_specialization_marker]`
- `#[marker]`
- `#[fundamental]`
- `#[rustc_paren_sugar]`
- `#[rustc_allow_incoherent_impl]`
- `#[rustc_coherence_is_core]`
This also changes `#[marker]` to error on duplicates instead of warning.
cc rust-lang/rust#142838, but I don't think it matters too much, since it's unstable.

Make UB transmutes really UB in LLVM
Ralf suggested in <https://github.com/rust-lang/rust/pull/143410#discussion_r2184928123> that UB transmutes shouldn't be trapping, which happened for the one path *that* PR was changing, but there's another path as well, so *this* PR changes that other path to match.

fix: Include frontmatter in -Zunpretty output
In the implementation (rust-lang/rust#140035), this was left as an open question for
the tracking issue (rust-lang/rust#136889). My assumption is that this should be
carried over.
The test was carried over from rust-lang/rust#137193 which was superseded by rust-lang/rust#140035.
Thankfully, either way, `-Zunpretty` is unstable and we can always
change it even if we stabilize frontmatter.
chore: Improve how the other suggestions message gets rendered
Note: This change is part of my ongoing work to use `annotate-snippets` as `rustc`'s emitter
This change started as a way to remove some specialty code paths from `annotate-snippets`, by making the "and {} other candidates" message get rendered like a secondary message with no level, but turned into a fix for the message's Unicode output. Before this change, when using the Unicode output, the other suggestions message would get rendered outside of the main suggestion block, making it feel disconnected from what it was referring to. This change makes it so that the message is on the last line of the block, aligning its rendering with other secondary messages, and making it clear what the message is referring to.

Some `tests/ui/` housekeeping, to trim down number of tests directly under `tests/ui/`. Part of rust-lang/rust#133895.

Properly track the depth when expanding free alias types
Decrease the depth after the fold so as not to affect the depth for unrelated same-level constituent types. My bad.
Fixesrust-lang/rust#142419.
Rework borrowing suggestions to use `Expr` instead of just `Span`
In the suggestion machinery for borrowing expressions and types, always use the available obligation `Span` to find the appropriate `Expr` to perform appropriateness checks no the `ExprKind` instead of on the textual snippet corresponding to the `Span`. (We were already doing this, but only for a subset of cases.) This now better handles situations where parentheses and `<>` are needed for correct syntax (`&(foo + bar)`, `(&foo).bar()`, `<&Foo>::bar()`, etc.).
Unify the logic for the case where `&` *and* `&mut` are appropriate with the logic for only one of those cases. (Instead of having two branches for emitting the suggestion, we now have a single one, using `Diag::multipart_suggestions` always.)
Handle the case when `S::foo()` should have been `<&S>::foo()` (instead of suggesting the prior `&S::foo()`. Fixrust-lang/rust#143393.
Make `Diag::multipart_suggestions` always verbose. CC rust-lang/rust#141973.
[rustdoc-json] Add tests for `#[doc(hidden)]` handling of items.
Add tests which check:
- `#[doc(hidden)]` items are not present in rustdoc JSON output by default.
- Invoking rustdoc with `--document-hidden-items` makes `#[doc(hidden)]` items appear, and they show their `#[doc(hidden)]` status appropriately.

Constify `Fn*` traits

this should unlock a few things. A few `const_closures` tests have broken even more than before, but that feature is marked as incomplete anyway

emit `.att_syntax` when global/naked asm use that option
fixes https://github.com/rust-lang/rust/issues/143542
LLVM would error when using `-Cllvm-args=-x86-asm-syntax=intel` in combination with global/naked assembly with `att_syntax`. It turns out that for LLVM you do in this case need to emit `.att_syntax`.

Fix weird rustdoc output when single and glob reexport conflict on a name
Fixesrust-lang/rust#143107.
The problem was that the second reexport would overwrite the first, leading to having unexpected results. To fix it, I now group items by their original `DefId` and their name and keep tracks of all imports for this item (should very rarely be more than one though, and even less often more than 2).

use `--dynamic-list` for exporting executable symbols
closesrust-lang/rust#101610
cc rust-lang/rust#84161https://sourceware.org/binutils/docs-2.39/ld/VERSION.html:
> --dynamic-list=dynamic-list-file
Specify the name of a dynamic list file to the linker. This is typically used when creating shared libraries to specify a list of global symbols whose references shouldn’t be bound to the definition within the shared library, or creating dynamically linked executables to specify a list of symbols which should be added to the symbol table in the executable. This option is only meaningful on ELF platforms which support shared libraries.
`ld.lld --help`:
> --dynamic-list=<file>: Similar to --export-dynamic-symbol-list. When creating a shared object, this additionally implies -Bsymbolic but does not set DF_SYMBOLIC
> --export-dynamic-symbol-list=file: Read a list of dynamic symbol patterns. Apply --export-dynamic-symbol on each pattern
> --export-dynamic-symbol=glob: (executable) Put matched symbols in the dynamic symbol table. (shared object) References to matched non-local STV_DEFAULT symbols shouldn't be bound to definitions within the shared object. Does not imply -Bsymbolic.
> --export-dynamic: Put symbols in the dynamic symbol table
Use `--dynamic-list` because it's older than `--export-dynamic-symbol-list` (binutils 2.35)

Assorted `run-make-support` maintenance
This PR should contain no functional changes.
- Commit 1: Removes the support library's CHANGELOG. In the very beginning, I thought maybe we would try to version this library. But this is a purely internal test support library, and it's just extra busywork trying to maintain changelog/versions. It's also hopelessly outdated.
- Commit 2: Resets version number to `0.0.0`. Ditto on busywork.
- Commit 3: Bump `run-make-support` to Edition 2024. The support library was already "compliant" with Edition 2024.
- Commit 4: Slightly organizes the support library dependencies.
- Commit 5: Previously, I tried hopelessly to maintain some manual formatting, but that was annoying because it required skipping rustfmt (so export ordering etc. could not be extra formatted). Give up, and do some rearrangements / module prefix tricks to get the `lib.rs` looking at least *reasonable*. IMO this is not a strict improvement, but I rather regain the ability to auto-format it with rustfmt.
- Commit {6,7}: Noticed in rust-lang/rust#143669 that we apparently had *both* {`is_msvc`, `is_windows_msvc`}. This PR removes `is_msvc` in favor of `is_windows_msvc` to make it unambiguous (and only retain one way of gating) as there are some UEFI targets which are MSVC but not Windows.
Best reviewed commit-by-commit.

Re-expose nested bodies in rustc_borrowck::consumers
After https://github.com/rust-lang/rust/pull/138499, it's not possible anymore to get borrowck information for nested bodies via `get_body_with_borrowck_facts`. This PR re-exposes nested bodies by returning a map containing the typeck root and all its nested bodies. To collect the bodies, a map is added to `BorrowCheckRootCtxt`, and a body is inserted every time `do_mir_borrowck` is called.
