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.

resolve: Turn the "non-empty glob must import something" error into a lint
This fixes#62334 by changing the error to a lint warning the glob. I changed the test but I'm very unsure of what I did as I do not know how to correctly check for the warning
