[rustdoc] Display unsafe attrs with edition 2024 `unsafe()` wrappers.
Use Rust 2024 edition representation for unsafe attributes in rustdoc HTML:
- `#[no_mangle]` -> `#[unsafe(no_mangle)]`
- `#[export_name = "foo"]` -> `#[unsafe(export_name = "foo")]`
- `#[link_section = ".text"]` -> `#[unsafe(link_section = ".text")]`
The 2024 edition representation is used regardless of the crate's own edition. This ensures that Rustaceans don't have to learn the rules of an outdated edition (e.g. that `unsafe()` wasn't always necessary) in order to understand a crate's documentation.
After some looking through the `T-rustdoc` issues, I was not able to find an existing issue for this. Apologies if I missed it.

lolbinarycat:rustdoc-intra-doc-link-warn-more-54191, r=GuillaumeGomez
get rid of some false negatives in rustdoc::broken_intra_doc_links
rustdoc will not try to do intra-doc linking if the "path" of a link looks too much like a "real url".
however, only inline links (`[text](url)`) can actually contain a url, other types of links (reference links, shortcut links) contain a *reference* which is later resolved to an actual url.
the "path" in this case cannot be a url, and therefore it should not be skipped due to looking like a url.
fixes https://github.com/rust-lang/rust/issues/54191
to minimize the number of false positives that will be introduced, the following heuristic is used:
If there's no backticks, be lenient revert to old behavior.
This is to prevent churn by linting on stuff that isn't meant to be a link.
only shortcut links have simple enough syntax that they
are likely to be written accidentlly, collapsed and reference links
need 4 metachars, and reference links will not usually use
backticks in the reference name.
therefore, only shortcut syntax gets the lenient behavior.
here's a truth table for how link kinds that cannot be urls are handled:
| | is shortcut link | not shortcut link |
|--------------|--------------------|-------------------|
| has backtick | never ignore | never ignore |
| no backtick | ignore if url-like | never ignore |

Simplify library dependencies on `compiler-builtins`
The three panic-related library crates need to have access to `core`, and `compiler-builtins` needs to be in the crate graph. Rather than specifying both dependencies, switch these crates to use `rustc-std-workspace-core` which already does this.
This means there is now a single place that the `compiler-builtins` dependency needs to get configured, for everything other than `alloc` and `std`.
The second commit removes `compiler-builtins` from `std` (more details in the message).

Uniform `enter_trace_span!` and add documentation
1. The latest changes to `enter_trace_span!` were ported from Miri (see https://github.com/rust-lang/miri/pull/4452#discussion_r2204958019), so now both the `rustc_const_eval` and the Miri macro accept the same syntax. Furthermore, the Miri macro was changed to just call rustc_const_eval`'s, to avoid duplication.
2. I made the `layout_of` (& friends) calls use that new syntax, e.g. `enter_trace_span!(layouting::layout_of, ...)`
3. I made sure the macro specifies all types/traits/macros it refers to using `$crate::`, so the macro works anywhere independently of which types/traits/macros are imported in the context it is used in.
4. I added documentation, examples and tips to the macro's doc. To make the rustdoc compile I had to add some hidden lines (`#`), but now it acts as a compilation test which will avoid reintroducing issue 3. in the future. I will also create a documentation file with everything one needs to know about tracing at a later point, but I figured adding some of that info directly on the tracing macro makes it more discoverable.
5. In `stack.rs` I made it so that the `"frame"` span has a field named "frame" (instead of "message") with the data about the frame. This field used to be called "message" (tracing's default) since it was previously formatted using `"{}", instance`, and now I replaced it with `frame = %instance`.

Make `libtest::ERROR_EXIT_CODE` const public to not redefine it in rustdoc
I think it's better to make this constant public so it can be used by crates using `libtest` as dependency.
As a side-note, I will update https://github.com/rust-lang/rust/pull/143900 to make use of this constant once this is current PR is merged.

Fix linker-plugin-lto only doing thin lto
When rust provides LLVM bitcode files to lld and the bitcode contains
function summaries as used for thin lto, lld defaults to using thin lto.
This prevents some optimizations that are only applied for fat lto.
We solve this by not creating function summaries when fat lto is
enabled. The bitcode for the module is just directly written out.
An alternative solution would be to set the `ThinLTO=0` module flag to
signal lld to do fat lto.
The code in clang that sets this flag is here:
https://github.com/llvm/llvm-project/blob/560149b5e3c891c64899e9912e29467a69dc3a4c/clang/lib/CodeGen/BackendUtil.cpp#L1150
The code in LLVM that queries the flag and defaults to thin lto if not
set is here:
https://github.com/llvm/llvm-project/blob/e258bca9505f35e0a22cb213a305eea9b76d11ea/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp#L4441-L4446

This commit changes it to store a `Region` instead of a `RegionVid` for the `Var` cases:
- We avoid having to call `Region::new_var` to re-create `Region`s from
`RegionVid`s in a few places, avoiding the interning process, giving a
small perf win. (At the cost of the type allowing some invalid
combinations of values.)
- All the cases now store two `Region`s, so the commit also separates
the `ConstraintKind` (a new type) from the `sub` and `sup` arguments
in `Constraint`.

There are identical definitions in `rustc_type_ir` and `rustc_ast`. This
commit removes them and places a single definition in `rustc_ast_ir`.
This requires adding `rust_span` as a dependency of `rustc_ast_ir`, but
means a bunch of silly conversion functions can be removed.
The one annoying wrinkle is that the old version had differences in
their `Debug` impls, e.g. one printed `u32` while the other printed
`U32`. Some compiler error messages rely on the former (yuk), and some
clippy output depends on the latter. So the commit also changes clippy
to not rely on `Debug` and just implement what it needs itself.

Reject running `compiletest` self-tests against stage 0 rustc unless explicitly allowed
Currently, in `pr-check-1`, we run `python3 ../x.py test --stage 0 src/tools/compiletest`, which is `compiletest` self-tests against stage 0 rustc. This makes it very annoying for PRs wanting to change target spec JSON format, which `compiletest` depends on for target information, as otherwise `compiletest` would have to know how to handle 2 different target spec JSON formats and know when to pick which.
Instead of doing that, we change `compiletest` self-tests to reject running against stage 0 `rustc` *unless* explicitly allowed with `build.compiletest-allow-stage0=true`. `build.compiletest-allow-stage0` is a proper bootstrap config option in favor of the ad-hoc `COMPILETEST_FORCE_STAGE0` env var. This means that:
- `./x test src/tools/compiletest --stage=0` is not allowed, unless `build.compiletest-allow-stage0=true` is set. In this scenario, `compiletest` self-tests should be expected to fail unless the stage 0 `rustc` as provided is like codegen_cranelift where it's *actually* built from in-tree `rustc` sources.
- In CI, we change `./x test src/tools/compiletest --stage=0` to `./x test src/tools/compiletest --stage=1`, and move it to `pr-check-2`. Yes, this involves building the stage 1 compiler, but `pr-check-2` already has to build stage 1 compiler to test stage 1 library crates.
- Crucially, this means that **`compiletest` is only intended to support one target spec JSON format**, namely the one corresponding to the in-tree `rustc`.
- This should preserve the `compiletest-use-stage0-libtest` UX optimization where changing `compiler/` tree should still not require rebuilding `compiletest` as long as `build.compiletest-use-stage0-libtest=true`, as that should remain orthogonal. This is completely unlike my previous attempt at https://github.com/rust-lang/rust/pull/144563 that tries to do a way more invasive change which would cause the rebuild problem.
Best reviewed commit-by-commit.

Support multiple crate versions in --extern-html-root-url
Rustdoc's `--extern-html-root-url` used to use `tcx.crate_name()` to identify crates, but that used crates' internal names from their metadata, instead of names given to them in `--extern`. That was confusing, because both `--extern…` arguments seem related and use similar syntax. Crucially, this didn't work correctly with Cargo's package aliases or multiple versions of crates.
`sess.opts.externs` lacks `CrateNum`, and `Resolver.extern_prelude` gets destroyed before `rustdoc` has a chance to see it, so I've had to save this mapping in `CStore`.
Just in case, I've kept the previous mapping by crate name as a fallback for crates that weren't matched by their extern name.
Fixes rust-lang/rust#76296

And move `./x test compiletest --stage=1` to `pr-check-2`, where testing
library artifacts already requires building the stage 1 compiler.

Otherwise, `compiletest` would have to know e.g. how to parse two
different target spec, if target spec format was changed between beta
`rustc` and in-tree `rustc`.

compiletest: Move directive names back into a separate file
This list no longer needs to be included in multiple crates, but having the list in its own file makes it easier to find and update when necessary.

Verify llvm-needs-components are not empty and match the --target value
I recently discovered a test with an empty `llvm-needs-components` entry (fixed in rust-lang/rust#143979) which meant that it didn't work correctly when building Rust with a limited set of LLVM targets.
This change makes a pair of improvements to prevent this issue from creeping in again:
* When parsing directives with values, `compiletest` will now raise an error if there is an empty value.
* Improved the `target_specific_tests` tidy checker to map targets to LLVM components, to verify that any existing `llvm-needs-components` contains the target being used.
I also fixed all the issues flagged by the improved tidy checker.

Free disk space on Windows 2025 runners
I've managed to reduce the time deletion takes by:
- Using powershell, which is generally faster for filesystem operations than msys2
- Performing deletions concurrently then waiting for them all to complete
It still takes 2-10 mins but that's not too bad.
