CI: use aws codebuild for job dist-arm-linux

|
The new git tests should be enough to check this scenario. We should ideally not be creating dummy commits on CI.

Ubuntu 25.04 has `llvm-20` packages that we can start testing with.
The `Dockerfile` is otherwise the same as the `llvm-18`/`19` runners.

make it possible to use stage0 libtest on compiletest
With https://github.com/rust-lang/rust/pull/119899, building the library tree will require a stage 1 compiler. This is because `compiletest` is defined as a `ToolStd` (since https://github.com/rust-lang/rust/pull/68019) in order to use the in-tree library. As a result, https://github.com/rust-lang/rust/pull/119899 makes certain development workflows more difficult as changes on the compiler tree will now require recompiling `compiletest` each time.
This PR allows switching `ToolStd` to `ToolBootstrap` with a simple boolean option in `bootstrap.toml` to allow `compiletest` to use the stage 0 `libtest` instead.
The changes under `src/ci` are clearly intended to make sure that `compiletest` doesn't break during future bootstrap beta bumps.

In accordance with RFC 3771.
I also added a stub doc page for the target and renamed the
windows-gnullvm page for consistency.

Build GCC on CI with GCC, not Clang
It seems that GCC built with Clang misbehaves. I have tested that cg_gcc tests [pass](https://github.com/rust-lang/rust/actions/runs/13842365913/job/38732750617?pr=138451) on CI with a downloaded GCC that was built in this way.
Prerequisite for https://github.com/rust-lang/rust/pull/138395.

Build GCC on CI
Previously, we have downloaded a specific commit of GCC and prebuilt it inside Docker using the `build-gccjit.sh` script. This PR removes that scripts and uses the bootstrap GCC step. This allows us to use the `src/gcc` submodule for determining which GCC should be built, and it also moves the logic closer to LLVM, which is also built by bootstrap.
A few things to note:
- The `sccache` option is currently in the `llvm` block, so the GCC build uses `llvm.ccache`, which is a bit weird :) We could either add `gcc.ccache`, or (what I think would be better) to just move `ccache` to the `build` section, as I don't think that it will be necessary to use ccache for LLVM, but not for GCC.
- When the GCC codegen backend is built, it needs to depend on a step that first builds GCC. This is currently done in a hacky way. The proper solution is to create a separate step for the GCC codegen backend, but that is a larger change. Let me know what you think.

The medium code model is already the default on the Rust side.
Make sure that linked in C objects (e.g. from glibc) also use
medium code model.

It is apparently required to download GCC dependencies.

Revert "CI: build FreeBSD artifacts on FreeBSD 13.4"
This reverts commit cf34545720986d99712e3b542e8f395360c75095.
That commit led to a regression of
https://github.com/rust-lang/rust/issues/132185 . So my analysis that the problem lay in FreeBSD 13.2's specific LLVM version was clearly wrong. Revert that commit until we can figure out the real root cause.
Fixes #132185

rustdoc: add nobuild typescript checking to our JS
By nobuild, I mean that the type annotations are all [in comments], not in the "native" typescript syntax. This is a bit uglier, but it lets you rapid-prototype without tsc, works with all the native browser debugging tools, and keeps Node out of Rust's bootstrap chain.
[in comments]: https://news.ycombinator.com/item?id=35892250
This pull request mostly just adds ts-ignore annotations and type declarations. To actually take good advantage of typescript, we'll want to "burn down" this pile of unsafe code until we eventually have a version with almost none of these.
This PR also adds tsc to the mingw-check Dockerfile, so that it can't fall out of date like the Closure annotations did.

Make it possible to build GCC on CI
This is the first step towards eventually enabling download of precompiled GCC from our CI.
Currently, we prebuild `libgccjit` on CI and cache it in Docker. This PR improves the bootstrap GCC step to make it work on CI, and also to make it faster by using sccache. After this change, an actual build on CI should take only 2-3 minutes.
Note that this PR does not yet remove the `build-gccjit.sh` script and replace it with the bootstrap step, I'll leave that to a follow-up PR.
The added `flex` package and the ZSTD library fix were needed to make GCC build on CI.

CI: build FreeBSD artifacts on FreeBSD 13.4
13.2 is EoL, and 13.3 will be EoL too in about 2 months. Plus, both suffer from a bug in LLVM's libunwind. It causes a segfault inside of std::backtrace::Backtrace::capture().
Fixes #132185
cc ``````@ehuss`````` . before you can do the trybuild, you'll also have to download new FreeBSD 13.4 base.txz images and place them in https://ci-mirrors.rust-lang.org/rustc , then update this PR with the correct file names.

Drop MIPS glibc 2.23 patches that reside in crosstool-ng now
These patches were added to crosstool-ng in https://github.com/crosstool-ng/crosstool-ng/commit/b88d3385162415294cba57e7b4cecc03259548fb and are therefore duplicate and fail to apply, breaking builds of `dist-mips*-linux`.
I have compile tested `dist-mipsel-linux`, I assume the other targets will work just as fine now.

This advances Fuchsia to a checkout from 2025-01-13, which corresponds
to a recent Rust roll, and hopefully avoids #135667, where a repository
used by the older version of Rust was accidentally archived and broke
checking out the prior version.

Move the dist-aarch64-linux CI job to an aarch64 runner instead of
cross-compiling it from an x86 one. This will make it possible to
perform optimisations such as LTO, PGO and BOLT later on.

CI: Add LTO support to clang in dist-x86_64-linux
After https://github.com/rust-lang/cc-rs/pull/1279, we attempt to pass `-flto=thin` to clang. In `dist-x86_64-linux`, we don't build clang with the `LLVMgold.so` library so this fails. This attempts to resolve this
First, pass the binutils plugin include directory to Clang, [which will build the library](https://github.com/llvm/llvm-project/blob/2d6d723a85c2d007b0359c206d66cd2e5a9f00e1/llvm/docs/GoldPlugin.rst#how-to-build-it)
Second, this library depends on the *version of libstdc++ that we built* specifically. However, despite both the RPATH and LD_LIBRARY_PATH pointing to `/rustroot/lib`, we incorrectly resolve to the system libstdc++, which doesn't load.
```
# LD_DEBUG=libs,files
2219: file=libstdc++.so.6 [0]; needed by /rustroot/bin/../lib/LLVMgold.so [0]
2219: find library=libstdc++.so.6 [0]; searching
2219: search path=/rustroot/bin/../lib/../lib (RPATH from file /rustroot/bin/../lib/LLVMgold.so)
2219: trying file=/rustroot/bin/../lib/../lib/libstdc++.so.6
2219: search path=/usr/lib64/tls:/usr/lib64 (system search path)
2219: trying file=/usr/lib64/tls/libstdc++.so.6
2219: trying file=/usr/lib64/libstdc++.so.6
```
Using `LD_PRELOAD` causes it to correctly load the library
I think this is probably not the most maintainable way to do this, so opening to see if this is desired and if there's a better way of doing this
