7455aa5395 Auto merge of #114457 - lcnr:trait_ref_is_knowable-normalize, r=compiler-errors
normalize in `trait_ref_is_knowable` in new solver

fixes https://github.com/rust-lang/trait-system-refactor-initiative/issues/51

Alternatively we could avoid normalizing the self type and do this at the end of the `assemble_candidates_via_self_ty` stack by splitting candidates into:
- applicable without normalizing self type
- applicable for aliases, even if they can be normalized
- applicable for stuff which cannot get normalized further

I don't think this would have any significant benefits and it also seems non-trivial to avoid normalizing only the self type in `trait_ref_is_knowable`.

49af618ef9 Auto merge of #114739 - lcnr:int-infer-impls, r=compiler-errors
remove builtin `Copy` and `Clone` impl for float and int infer

it's only change is whether `{integer}: Copy` is ambiguous, this has the following properties

- these goals get proven earlier, potentially resulting in slightly better perf
- it causes inconsistent behavior and ICE if there do not exist impls for all integers, causing issues when using `#[no_core]`
- it means `Clone` has user-facing differences from other traits from `core` with the new solver because it can potentially guide inference there
- it's just very sus™ to have a builtin impl which applies during type inference but not afterwards

CI: fix Docker layer caching

As reported by `@klensy` on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/docker.20images.20always.20rebuilded), Github Actions have recently updated their Docker version from 20.x to 23.x, which enabled the BuildKit build backend by default.

This broke our way of performing Docker layer caching on CI, which immediately made all non-PR CI builds (including try builds) ~1 hour longer (Docker caching didn't work on PR builds before, so it wasn't affected). The moment this started happening can be seen [here](https://github.com/rust-lang-ci/rust/actions?page=2&query=branch%3Aauto+is%3Asuccess).

The problem is with the following command:
```
docker history -q rust-ci | \
          grep -v missing | \
          xargs docker save | \
          gzip | \
          $upload
```
which returns the intermediate layers as `<missing>`, if BuildKit is enabled. This was investigated by `@klensy` in https://github.com/rust-lang/rust/pull/114621. Thanks for that!

I will continue experimenting with how we can enable the cache with BuildKit in https://github.com/rust-lang/rust/pull/114762, but for the time being, I think that we should just hotfix this.

This PR reverts the build backend back to the old one, which fixes the caching. However, we also have to bust the cache of all Dockerfiles, otherwise caching would only start kicking in for them the next time they are updated (or the next time GH updates their docker version). Because when the Docker version was updated the last time, the Dockerfiles were cached on S3 with basically an empty cache, and unless we bust it, even after reverting to the old build engine, the CI script would just download the empty cache and rebuild the Dockerfile from scratch, thus nullifying our fix.

1e836d12d3 Auto merge of #114710 - Urgau:fix-expect-dead_code-114557, r=cjgillot
Respect `#[expect]` the same way `#[allow]` is with the `dead_code` lint

This PR makes the `#[expect]` attribute being respected in the same way the `#[allow]` attribute is with the `dead_code` lint.

The fix is much more involved than I would have liked (and it's not because I didn't tried!), because the implementation took advantage of the fact that firing a lint in a allow context is a nop (for the user, as the lint is suppressed) to not fire-it at all.

And will it's fine for `#[allow]`, it definitively isn't for `#[expect]`, as the presence and absence of the lint is significant. So a big part of the PR is just adding the context information of whenever an item is on the worklist because of an `[allow]`/`#[expect]` or not.

Rollup merge of #114692 - lcnr:internal_features-warn, r=Nilstrieb
downgrade `internal_features` to warn

Not sure if this requires an FCP or whatever. By having the lint as deny I need to modify test cases when testing them outside of the test suite as the test suite implicitly allows the lint. This takes maybe 10 to 20 seconds per test, but given just how frequently I end up copying tests to different repos it's a significant annoyance.

Record binder for bare trait object in LifetimeCollectVisitor
