add aarch64-unknown-teeos target
TEEOS is a mini os run in TrustZone, for trusted/security apps. The libc of TEEOS is a part of musl. The kernel of TEEOS is micro kernel.
This MR is to add a target for teeos.
MRs for libc and rust-std are in progress.

misc bootstrap cleanups
- rename `detail_exit_macro` to `exit`
- remove unnecessary `Builder::new_standalone` function
- support `x suggest` with build-metrics
This does three things:
1. Remove `forward!(Build, fn try_run())`. Having `try_run` behave differently as a free function than an associated function is confusing, and `Builder::try_run` is a very desirable name.
2. Move `test::try_run` and `run::try_run` to `Builder::try_run`. These functions are different than `Config::try_run` - they delay the failure and print it out at the end of the build.
3. Mark `Config::try_run` as deprecated to encourage people to use `Builder::try_run` instead.
This caught several places which weren't waiting until the command finished to drop the Group.
I also took the liberty of calling `msg_sysroot_tool` from `run_cargo_test` to reduce code duplication and make errors like this less likely in the future.
If:
1. The current branch has the same name as git tag, and
2. The current branch is set to track a remote other than `origin`, and
3. We try to update a submodule
then we'll get the following error:
```
; x c
Updating submodule src/doc/reference
remote: Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
fatal: 'personal' does not appear to be a git repository
fatal: Could not read from remote repository.
```
The problem is that 1. causes `git symbolic-ref --short HEAD` to try and disambiguate the branch
from the tag using `heads/branch-name`, which breaks a previous workaround for a bug in `git
submodule update` that uses the wrong remote.
Adapt the workaround to strip `heads/` from the output.
In particular, this hides compiletest suites under a dropdown - some builders are configured with `verbose-tests`, which makes the suites take up many thousands of lines.
before:
```
Documenting stage1 cargo (x86_64-unknown-linux-gnu)
Check compiletest suite=rustdoc-js mode=js-doc-test (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu)
```
after:
```
::group::Documenting stage1 cargo (x86_64-unknown-linux-gnu)
::group::Testing stage1 compiletest suite=rustdoc-js mode=js-doc-test (x86_64-unknown-linux-gnu)
```
Some targets are added to these hashmaps at runtime, and are not present
during dry runs. To avoid errors, this commit changes all the related
functions to always return empty strings/paths during dry runs.
Run tests on PGO/LTO/BOLT optimized dist artifacts
This PR adds baisc tests for the optimized dist builds on x64 Linux and Windows. A subset of the test suite is run, so it's not perfect, but it's better than the status quo (which is basically no testing at all, apart from the perf bot on Linux).
r? `@ghost`
This makes it more clear that we're using stage 0 *to document* rustc, not that we're documenting
stage0 rustc itself.
It also fixes a bug in `msg_sysroot_tool` that would print `Docing`, and removes the `Debug` impl
for `Kind` to make sure it doesn't happen again.
Before:
```
Documenting stage0 compiler {rustc-main} (aarch64-apple-darwin)
```
After:
```
Documenting compiler {rustc-main} (stage0 -> stage1, aarch64-apple-darwin)
```
enhancements on build_helper utilization and rustdoc-gui-test
This change provides codebase improvements, resolves `FIXME` in `rustdoc-gui-test` and makes `rustdoc-gui` test able to find local `node_modules` directory outside of the source root.
This reverts commit 9267843e72, reversing
changes made to e52fbff5e8.
This breaks our ability to bump the src/version where we're bootstrapping with an older compiler
than usual (according to version number). It's not clear whether the intended use case has a clean
solution given this constraint, so reverting for now - we can reland with a fix of some kind implemented.
- Use `cargo metadata` to determine whether a crate has a library
package or not
- Collect metadata for all workspaces, not just the root workspace and
cargo
- Don't pass `--lib` for crates without a library
- Use `run_cargo_test` for rust-installer
- Don't build documentation in `lint-docs` if `--no-doc` is passed
Create "suggested tests" tool in `rustbuild`
Not the claimed person in #97339 but:
I've done a very rough implementation of this feature in-tree. I'm very new to `rustc` development (outside of docs) so some help would be greatly appreciated. The UI of this new subcommand obviously will change and I need some mentoring with the `--run` flag.

Initial support for loongarch64-unknown-linux-gnu
Hi, We hope to add a new port in rust for LoongArch.
LoongArch intro
LoongArch is a RISC style ISA which is independently designed by Loongson
Technology in China. It is divided into two versions, the 32-bit version (LA32)
and the 64-bit version (LA64). LA64 applications have application-level
backward binary compatibility with LA32 applications. LoongArch is composed of
a basic part (Loongson Base) and an expanded part. The expansion part includes
Loongson Binary Translation (LBT), Loongson VirtualiZation (LVZ), Loongson SIMD
EXtension (LSX) and Loongson Advanced SIMD EXtension(LASX).
Currently the LA464 processor core supports LoongArch ISA and the Loongson
3A5000 processor integrates 4 64-bit LA464 cores. LA464 is a four-issue 64-bit
high-performance processor core. It can be used as a single core for high-end
embedded and desktop applications, or as a basic processor core to form an
on-chip multi-core system for server and high-performance machine applications.

Since last year, we have locally adapted two versions of rust, rust1.41 and rust1.57, and completed the test locally.
I'm not sure if I'm submitting all the patches at once, so I split up the patches and here's one of the commits
