Print the full arguments passed to `./configure` in CI
This is useful to replicate CI failures locally. Before, the arguments would be truncated and it would be hard to tell what it was actually doing.
Before:
```
configure: build.configure-args := ['--build=x86_64-unknown-linux-gnu', '--save-t ...
```
After:
```
configure: build.configure-args := ['--build=x86_64-unknown-linux-gnu', '--save-toolstates=/tmp/toolstate/toolstates.json', '--enable-verbose', '--enable-sccache', '--disable-manage-submodules', '--enable-locked-deps', '--enable-cargo-native-static', '--set', 'rust.codegen-units-std=1', '--set', 'dist.compression-profile=balanced', '--dist-compression-formats=xz', '--disable-dist-src', '--set', 'rust.download-rustc=if-unchanged', '--release-channel=nightly', '--enable-debug-assertions', '--enable-overflow-checks', '--enable-llvm-assertions', '--set', 'rust.verify-llvm-ir', '--set', 'llvm.download-ci-llvm=if-available', '--enable-missing-tools']
```
Fix bug where private item with intermediate doc hidden re-export was not inlined
This fixes this bug:
```rust
mod private {
/// Original.
pub struct Bar3;
}
/// Hidden.
#[doc(hidden)]
pub use crate::private::Bar3;
/// Visible.
pub use self::Bar3 as Reexport;
```
In this case, `private::Bar3` should be inlined and renamed `Reexport` but instead we have:
```
pub use self::Bar3 as Reexport;
```
and no links.
There were actually two issues: the first one is that we forgot to check if the next intermediate re-export was doc hidden. The second was that we made the `#[doc(hidden)]` attribute inheritable, which shouldn't be possible.

Revert "Enable incremental independent of stage"
This reverts commit 827f656ebb.
Incremental is not sound to use across stages. Arbitrary changes to the compiler can invalidate the incremental cache - even changes to normal queries, not incremental itself! - and we do not currently enable `incremental-verify-ich` in bootstrap. Since 2018, we highly recommend and nudge users towards stage 1 builds instead of stage 2, and using `keep-stage` for anything other than libstd is very rare.
I don't think the risk of unsoundness is worth the very minor speedup when building libstd. Disable incremental to avoid spurious panics and miscompilations when building with the stage 1 and 2 sysroot.
Combined with https://github.com/rust-lang/rust/pull/111329, this should fix https://github.com/rust-lang/rust/issues/76720.

Fix `x test core` when download-rustc is enabled
Fix `x test --stage 2 core` when download-rustc is enabled
This works by building std from source instead of downloading it, for library tests only.
This was somewhat complicated because of the following requirements:
1. Unconditionally downloading libstd breaks `x test core`, because `coretests` requires the std loaded from the sysroot to match the std that's currently being tested.
2. Unconditionally rebuilding libstd breaks `x test ui-fulldeps librustdoc`, because anything loading `rustc_private` needs to use the same libstd that rustc was built with.
Break the knot by introducing a new `stage2-test-sysroot`, used only for testing `std` itself. This
holds a freshly compiled std, while `stage2` and `ci-rustc-sysroot` still hold the downloaded std.
This also extends the existing `cp_filtered` in Sysroot to apply to the `rust-std` component, not just the `rustc-dev` component, to avoid having both versions of std in `stage2-test-sysroot`.
Fixes#110352.
update Miri
Also adjust Miri's compiletest a little: in pre-subtree days we added `-A unused -Astable-features` to have the Miri toolstate break less often. But nowadays it just causes confusion when Miri CI works in rustc but fails on the Miri side so let's get rid of this difference.

Add other workspaces to `linkedProjects` in rust_analyzer_settings
This makes go-to-definition, etc. work in cg_clif, cg_gcc, rust-analyzer, and src/tools/x.
QNX Neutrino: exponential backoff when fork/spawn needs a retry
Fixes#108594: When retrying, sleep with an exponential duration. When sleep duration is lower than minimum possible sleeping time, yield instead (this will not be often due to the exponential increase of duration).
Minimum possible sleeping time is determined using `libc::clock_getres` but only when spawn/fork failed the first time in a request. This is cached using a LazyLock.

Update dependencies with reported vulnerabilities
Vulnerable dependencies:
* bumpalo 3.12.1 (yanked)
* updated to 3.13.0
* tokio 1.8.4 - https://rustsec.org/advisories/RUSTSEC-2023-0001
* updated to 1.28.2
* remove_dir_all 0.5.3 - https://rustsec.org/advisories/RUSTSEC-2023-0018
* removed by using the standard library function in `rust-installer` instead and updating to `tempfile@3.5.0` (which also removes the dependency).
The new dependencies come from `tempfile@3.5.0` which adds the dependency on `rustix`

Fix the progress message for `x doc rustc`
This makes it more clear that we're using stage 0 *to document* rustc, not that we're documenting stage0 rustc itself.
It also fixes a bug in `msg_sysroot_tool` that would print `Docing`, and removes the `Debug` impl for `Kind` to make sure it doesn't happen again.
Before:
```
Documenting stage0 compiler {rustc-main} (aarch64-apple-darwin)
```
After:
```
Documenting compiler {rustc-main} (stage0 -> stage1, aarch64-apple-darwin)
```
thanks `@BoxyUwU` for catching this!
Add spans to `clippy.toml` error messages
Adds spans to errors and warnings encountered when parsing `clippy.toml`.
changelog: Errors and warnings generated when parsing `clippy.toml` now point to the location in the TOML file the error/warning occurred.
Require that const param tys implement `ConstParamTy`
1. Require that const param tys implement `ConstParamTy` instead of using `search_for_adt_const_param_violation`
2. Add `StructuralPartialEq` as a supertrait for `ConstParamTy`, since we need to make sure that we derive *both* `PartialEq` and `Eq`
3. Implement `ConstParamTy` for tuples up to 12 (or whatever the default for tuples is)
4. Add some custom diagnostics to `ConstParamTy` errors, to avoid regressions from (1.). It's still not as great as it could be -- will point out inline in comments.

Use translatable diagnostics in `rustc_const_eval`
This PR:
* adds a `no_span` parameter to `note` / `help` attributes when using `Subdiagnostic` to allow adding notes/helps without using a span
* has minor tweaks and changes to error messages

Do not build docs in try builds
This PR adds a new environment variable to the optimized build Python script, which causes it to ignore certain parts of the final `dist` build (mainly docs) in try builds. This reduces the duration of try builds by ~10 minutes.
