Fixes#109543. When checking paths in HIR typeck, we don't want to check
for const predicates since all we want might just be a function pointer.
Therefore we move this to MIR constck and check that bounds are met
during MIR constck.
[rust-installer] Allow long link names in tar files
Without this, users trying to run `x.py dist` under a sufficiently long path run into problems when we build the resulting tarballs due to length limits in the original tar spec. The error looks like:

The fix is to make use of the widely-supported GNU tar extensions which lift this restriction. Switching to [`tar::Builder::append_link`] takes care of that for us. See also alexcrichton/tar-rs#273.

Don't skip all directories when tidy-checking
This fixes a regression from https://github.com/rust-lang/rust/pull/108772 which basically made it that tidy style checks only `README.md` and `COMPILER_TESTS.md`.
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.
rustdoc: Fix ICE for intra-doc link on intermediate re-export
Fixes https://github.com/rust-lang/rust/issues/109282.
This PR is based on #109266 as it includes its commit to make this work.
`@petrochenkov:` It was exactly as you predicted, adding the `DefId` to the attributes fixed the error for intermediate re-exports as well. Thanks a lot!

Remove Nilstrieb from review rotation
I currently don't have enough time to be on rotation. You can still request a review from me and I may still steal PRs sometimes though.
Refactor: Separate `LocalRef` variant for not-evaluated-yet operands
As I was reading through this, I noticed that almost every place that was using this needed to distinguish between Some vs None in the match arm anyway, so thought that separating the cases at the variant level might be clearer instead.
I like how it ended up; let me know what you think!
Rename 'src/bootstrap/native.rs' to llvm.rs
Fixed#108240
Renamed 'native.rs' to 'llvm.rs', also moved `TestHelpers` to `test.rs`. Replaced all the `native.rs` occurrences at `src/bootstrap` files to `llvm.rs`
More config.toml.example cleanups
- Link to more documentation
- Move `changelog-seen` into the "Global Settings" section
- Update incorrect comments on `llvm.link-shared` and `rust.debug-assertions`
- Use the correct default in the commented-out example more often
- Clarify that `docs` and `compiler-docs` only control the default, they're not a hard-off switch.
- Document `-vvv` and `local-rebuild`
- Minor improvements to doc-comments in config.toml.example
This also sets `download-rustc = false`; that was already the default, but it will be helpful in case the default changes (https://jyn.dev/2023/01/12/Bootstrapping-Rust-in-2023.html).

Don't elaborate non-obligations into obligations
It's suspicious to elaborate a `PolyTraitRef` or `Predicate` into an `Obligation`, since the former does not have a param-env associated with it, but the latter does. This is a footgun that, while not being misused *currently* in the compiler, easily could be misused by someone less familiar with the elaborator's inner workings.
This PR just changes the API -- ideally, the elaborator wouldn't even have to deal with obligations if we're not elaborating obligations, but that would require a bit more abstraction than I could be bothered with today.
debuginfo: Get pointer size/align from tcx.data_layout instead of layout_of
This avoids some type interning and a query execution. It also just makes the code simpler.
Fix "Directly go to item in search if there is only one result" setting
Part of #66181.
The setting was actually broken, so I fixed it when I added the GUI test.

Stabilize `nonnull_slice_from_raw_parts`
FCP is done: https://github.com/rust-lang/rust/issues/71941#issuecomment-1100910416
Note that this doesn't const-stabilize `NonNull::slice_from_raw_parts` as `slice_from_raw_parts_mut` isn't const-stabilized yet. Given #67456 and #57349, it's not likely available soon, meanwhile, stabilizing only the feature makes some sense, I think.
Closes#71941
Cleanup `codegen_fn_attrs`
The `match` control flow construct has been stable since 1.0, we should use it here.
Sorry for the hard to review diff, I did try to at least split it into two commits. But looking at before-after side-by-side (instead of whatever github is doing) is probably the easiest way to make sure that I didn't forget about anything.
On top of #109088, you can wait for that
Limit to one link job on mingw builders
This is another attempt to work around
https://github.com/rust-lang/rust/issues/108227.
By limiting to one link job, we should be able to avoid file name clashes in mkstemp().
Add #[inline] to as_deref
While working on https://github.com/rust-lang/rust/pull/109247 I found an `as_deref` call in the compiler that should have been inlined. This fixes the missing inlining (but doesn't address the perf issues I was chasing).
r? `@thomcc`
Refactor: `VariantIdx::from_u32(0)` -> `FIRST_VARIANT`
Since structs are always `VariantIdx(0)`, there's a bunch of files where the only reason they had `VariantIdx` or `vec::Idx` imported at all was to get the first variant.
So this uses a constant for that, and adds some doc-comments to `VariantIdx` while I'm there, since [it doesn't have any today](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_target/abi/struct.VariantIdx.html).
