Change the tidy license checker
This adds a bunch of licenses to the global list of allowed licenses that are at least as permissive as some other license in the list. In addition it adds another list for licenses that are allowed to be used by tools, but not by the runtime. All permissive licenses from the exception lists are added here. This makes it clearer what actual exceptions to our permissive licensing policy are and will hopefully make it a bit easier to review future changes to the list of licenses rather than just adding whatever license is necessary to the global list of allowed licenses or to the list of exceptions.
compiletest: Store the selected edition in `TestProps`
While working on a larger overhaul of directive processing, I ran into difficulty with the `has_edition` local variable.
Storing the selected edition in `TestProps` should make it easier to extract parts of directive processing into independent handler functions, because the `//@ edition` handler won't need access to additional mutable state outside of `TestProps`.
We still automatically add the edition to `compile_flags`, because there is too much existing compiletest code relying on that behaviour.

compiletest: Move `AuxProps` out of `EarlyProps`
The primary purpose of `EarlyProps` is to discover revisions, so that we can create a separate test structure for each revision.
Revisions can (and do) have different auxiliaries, and up-to-date checking is already done per-revision, so it makes more sense to perform up-to-date checks based on the current revisions's auxiliaries only.

enzyme/autodiff is compatible with download-ci=true
To my surprise autodiff just works out of the box with download-ci=true. Thanks to all the bootstrap people who over the past helped me to link properly against the sysroot LLVM, which seems to pay off here.
That also helps with enabling Rust in Enzyme CI, since CCache for some reason doesn't seem to cache LLVM correctly on their runners.
I verified that this works with
` ./configure --release-channel=nightly --enable-llvm-enzyme --enable-option-checking --disable-docs --enable-llvm-assertions --set llvm.download-ci-llvm=true`. However, shouldn't download-ci-llvm already be the default? Why do I still have to manually set it with this pr?
I tested it afterwards with
`./x.py test --stage 1 tests/codegen-llvm/autodiff`

compiletest: Include a file path in `DirectiveLine`
This avoids the need to laboriously pass a test/aux file path into dozens of directive parsing methods that already take a `DirectiveLine`.

Refactor move analysis subpath representation
Follow up to rust-lang/rust#147055
This PR does two things:
1. Document/validate move analysis's assumptions about `Subslice` projections
2. Decouple move paths from `ProjectionElem`, using a new enum `MoveSubPath` instead
- This would be needed eventually when `ProjectionElem::Deref` is removed
I wanted to do even more abstraction, making `MovePathLookup::find` return an iterator to remove the special handling of subslices in borrowck, but that regressed diagnostics and just wasn't worth the complexity.
rustdoc: Fix passes order so intra-doc links are collected after stripping passes
Fixes regression I introduced in https://github.com/rust-lang/rust/pull/147153.
This PR puts back the intra-doc link collecting pass after the stripping items pass, preventing lints to be emitted on non-visible items.
Although, might be nice to add a way to change this behaviour. To be discussed later on.

bootstrap: migrate to object 0.37
I noticed we had a mix of 0.37 and 0.36 at work, and this was why. As far as I can tell everything still builds and works correctly.
Limit impl_trait_header query to only trait impls
Changes `impl_trait_header` to panic on inherent impls intstead of returning None. A few downstream functions are split into option and non-option returning functions. This gets rid of a lot of unwraps where we know we have a trait impl, while there are still some cases where the Option is helpful.
Summary of changes to tcx methods:
* `impl_is_of_trait` (new)
* `impl_trait_header` -> `impl_trait_header`/`impl_opt_trait_header`
* `impl_trait_ref` -> `impl_trait_ref`/`impl_opt_trait_ref`
* `trait_id_of_impl` -> `impl_trait_id`/`impl_opt_trait_id`
style-guide: fix typo for empty struct advice
the advice appears to apply to empty structs with braces (parens/blocks), and a unit struct in the comment does not make sense. Fix the typo.
std: Add Motor OS std library port
Motor OS was added as a no-std Tier-3 target in
[PR 146848](https://github.com/rust-lang/rust/pull/146848) as x86_64-unknown-motor.
This PR adds the std library for Motor OS.
While the PR may seem large, all it does is proxy
std pal calls to [moto-rt](https://crates.io/crates/moto-rt). Where there is some non-trivial
code (e.g. thread::spawn), it is quite similar, often
identical, to what other platforms do.
