Module level docs should resolve intra-doc links as locally as
possible. As such, this commit alters the heuristic for finding
intra-doc links such that we attempt to resolve names mentioned
in *inner* documentation comments within the (sub-)module rather
that from the context of its parent.

This changes the mechanism of `-Z dual-proc-macro` to record the host
proc macro hash in the transistive dependency information and use it
during dependency resolution instead of resolving only by name.
ci: revert msys2 ca-certificates hack
The hack was added because upstream msys2 broke the ca-certificates package, but since then it has been fixed. This reverts CI to use the upstream package.

Update comments re type parameter hack in object safety
To check if a method's receiver type is object safe, we create a new receiver type by substituting in a bogus type parameter (let's call it `U`) for `Self`, and checking that the unmodified receiver type implements `DispatchFromDyn<receiver type with Self = U>`. It would be better to use `dyn Trait` directly, and the only reason we don't is because it triggers another check that `Trait` is object safe, resulting in a query cycle. Once the feature `object_safe_for_dispatch` (tracking issue https://github.com/rust-lang/rust/issues/43561) is stabilized, this will no longer be the case, and we'll be able to use `dyn Trait` as the unsized `Self` type. I've updated the comments in object_safety.rs accordingly.

Upload toolstates.json to rust-lang-ci2
This PR does two things:
* Following up with https://github.com/rust-lang/rust/pull/65202, it migrates deploying artifacts to CI in a script. Both uploading release artifacts and CPU stats were merged into the same script, designing it to be easily extended.
* Uploads the toolstate JSON to `rust-lang-ci2` along with the release artifacts, both for Linux and Windows. This is needed because @RalfJung wants to stop shipping MIRI when its tests are failing, and the toolstate repo doesn't have entries for each commit. Having the toolstate data (just for that specific commit) on `rust-lang-ci2` will simplify the code a lot.

submodules: Bump RLS to 58869107ec162a821a4bee53cdd3f51c84cda3ea
Most importantly it contains d267b49c2f which fixes the RLS build whenever Clippy is built successfully in Rust CI.
Closes#65944

Before this commit toolstates.json was stored in /tmp and it wasn't
mounted outside the build container. That caused uploading the file in
the upload-artifacts task to fail, as the file was missing on the host.
Mounting /tmp/toolstates.json alone is not the best approach: if the
file is missing when the container is started the Docker engine will
create a *directory* named /tmp/toolstates.json.
The Docker issue could be solved by pre-creating an empty file named
/tmp/toolstates.json, but doing that could cause problems if bootstrap
fails to generate the file and the toolstate scripts receive an empty
JSON.
The approach I took in this commit is to instead mount a /tmp/toolstate
directory inside Docker, and create the toolstates.json file in it. That
also required a small bootstrap change to ensure the directory is
created if it's missing.
The hack was added because upstream msys2 broke the ca-certificates
package, but since then it has been fixed. This reverts CI to use the
upstream package.

save-analysis: Account for async desugaring in async fn return types
Closes#65590
When visiting the return type of an async function we need to take into account its desugaring, since it introduces a new definition under which the return type is redefined.

Use rustc-workspace-hack for rustbook
As rustbook now depends transitively on openssl, it needs access to the
rustc-workspace-hack/all-static feature to pick up openssl-sys/vendored.
This fixes the rust build with `all-static = true` on systems where
openssl is not installed (e.g. when cross-compiling).
proc_macro: clean up bridge::client::__run_expand{1,2} a bit.
See commit titles/diffs for more details.
The first commit is made possible by #53451 being fixed (almost a year ago).
The last commit should remove the need for `#[allow(improper_ctypes)]` in #65134.
Re-enable Emscripten's exception handling support
Passes LLVM codegen and Emscripten link-time flags for exception
handling if and only if the panic strategy is `unwind`. Sets the
default panic strategy for Emscripten targets to `unwind`. Re-enables
tests that depend on unwinding support for Emscripten, including
`should_panic` tests.

ci: refactor pr tools job skipping
We have a job in our CI (PR's x86_64-gnu-tools) that's supposed to run only when a submodule is changed in the PR, and it works by having a task at the start of the build that skips all the following tasks if the condition isn't met.
Before this commit that task was gated with template parameters, which is a unique feature of Azure Pipelines. To make our CI more generic this commit switches the gate to use a simple environment variable plus a condition, which should be supported on more CI providers.
This PR also extracts the skipping logic into a script.
