(ci) Update macOS Xcode to 15
This updates the macOS builders to Xcode 15. The aarch64 images will be removing Xcode 14 and 16 very soon (https://github.com/actions/runner-images/issues/10703), so we will need to make the switch to continue operating. The linked issue also documents GitHub's new policy for how they will be updating Xcode in the future. Also worth being aware of is the future plans for x86 runners documented in https://github.com/actions/runner-images/issues/9255 and https://github.com/actions/runner-images/issues/10686, which will impact our future upgrade behaviors.
I decided to also update the Xcode in the x86_64 runners, even though they are not being removed. It felt better to me to have all macOS runners on the same (major) version of Xcode. However, note that the x86_64 runners do not have the latest version of 15 (15.4), so I left them at 15.2 (which is currently the default Xcode of the runner).
Xcode 15 was previously causing problems (see #121058) which seem to be resolved now. `@bjorn3` fixed the `invalid r_symbolnum` issue with cranelift. The issue with clang failing to link seems to be fixed, possibly by the update of the pre-built LLVM from 14 to llvm 15 in https://github.com/rust-lang/rust/pull/124850, or an update in our source version of LLVM. I have run some try builds and at least LLVM seems to build (I did not run any tests).
Closes#121058
ci update freebsd version proposal, freebsd 12 being eol
raising to the lowest still active supported freebsd version.
From 13.1 (already eol too), freebsd introduces a cpu affinity layer
with linux. It also introduces a api compatible copy_file_range which
can be used like its linux's counterpart.
The former is essential to build https://github.com/rust-lang/rust/pull/120589, therefore breaks the backward
compatibility with the previous FreeBSD releases.

`@rustbot` modify labels: rollup
[A recent commit in LLVM](ab930ee7ca) modified the JSON output of LLVM. The LLVM change renamed "Notes" to "NoteSections" and inserted a new "Notes" key nested under each "NoteSection".
This change shores up exceptions around reading the JSON output of llvm-readelf and reads from "NoteSections" instead of the non-existent "Notes".
force "HEAD" for non-CI and `git_upstream_merge_base` for CI environment
When rust-lang/rust is configured as remote, some of the git logic (for tracking changed files) that uses get_closest_merge_commit starts to produce annoying results as the upstream branch becomes outdated quickly (since it isn't updated with git pull). We can rely on HEAD for non-CI environments as we specifically treat bors commits as merge commits, which also exist on upstream. As for CI environments, we should use `git_upstream_merge_base` to correctly track modified files as bors commits may be in `HEAD` but not yet on the upstream remote.
This is also an alternative fix for https://github.com/rust-lang/rust/issues/129528 since https://github.com/rust-lang/rust/pull/131331 reverts the previous fix attempts.
Without this change, the markdown-style backticks are treated as a shell
command substitution, which fails like so:
/checkout/src/ci/run.sh: line 58: DISABLE_CI_RUSTC_IF_INCOMPATIBLE: command not found
debug: configured.
Enable `--no-sandbox` option by default for rustdoc GUI tests
It's apparently common enough for people to have issues with the `sandbox` mode in chromium, so better disable it by default.

[CI] Upload average CPU utilization of CI jobs to DataDog
This PR adds a new CI step that uploads the average CPU utilization of the current GH job to Datadog. I want to add more metrics in follow-up PRs.

Revert space-saving operations
The "all of our artifacts" `mv` seems like it may save enough space to matter sometimes, since it can range up to a gigabyte of difference, if memory serves. For the rest, I think we're good.

This partially reverts commit fe7c97c2e7.
I kept a mv, not a cp, for the one that shuffles major artifacts around,
because the size of those artifacts are big enough to matter, sometimes.
I don't think the diagnostic info will be that heavy, by comparison.
Use a small runner for msvc-ext2 job
Hopefully this should eliminate the errors from this job. The only question is how long it takes.

ci: add a runner for vanilla LLVM 19
Ubuntu 24.10 has `llvm-19` packages that we can start testing with.
The `Dockerfile` is otherwise the same as the `llvm-18` runner.
Distribute rustc_codegen_cranelift for Windows
With support for raw-dylib recently added to cg_clif, and inline assembly support working on Windows for quite a while now, all blockers for distributing cg_clif on Windows that I mentioned in https://github.com/rust-lang/rust/pull/81746#issuecomment-1774099637 are fixed now.
