Followup to https://github.com/rust-lang/rust/pull/103778
Sorry for the quick succession but this fixes one more building issue for Tier 3 `windows-gnullvm` that I have previously missed, and it would be nice to have it in the release.

Use clang for the UEFI targets
This fixes an issue where the C and asm sources built by compiler_builtins were being compiled as ELF objects instead of PE objects. This wasn't noticed before because it doesn't cause compiler_builtins or rustc to fail to build. You only see a failure when a program is built that references one of the symbols in an ELF object.
Compiling with clang fixes this because the cc crate converts the UEFI targets into Windows targets that clang understands, causing it to produce PE objects.
Also update compiler_builtins to 0.1.84 to pull in some necessary fixes for compiling the UEFI targets with clang.

Revert "Update CI to use Android NDK r25b"
This reverts commit bf7f1ca316a249cf99d722d79a0db12fef687142 (pull request #102332).
The relevant discussion can be found in #103673, where it was agreed that more time is needed to warn the community of the upcoming breakage.
This PR is for the `master` branch, where a conflict was recently introduced due to 6d8160261ff3aee3b6eaacc37ac96cafff530980. The conflict is in `cc_detect.rs`, where the code that corrects the target triple was moved to a new function called `ndk_compiler()`. This puts the old logic in the `ndk_compiler` function, and assumes that it works properly in the other location where that code is being called. I would appreciate review from ``@pietroalbini`` to understand how we can test that the reverted logic is also suitable for the additional use case (seems to be related to setting `cc` and `cxx`). I've confirmed already that with these changes I can compile for `armv7-linux-androideabi`, `aarch64-linux-android`, `i686-linux-android`, and `x86_64-linux-android` using `x.py`.
A separate revert for the `beta` branch will be required, since the original change has already made it to beta. The beta revert is available at https://github.com/alex-pinkus/rust/commit/3fa0d94674fbe37090ebe44ac1f06e2233f3121e, but I'm not sure of the process for staging that PR.

update ntapi dep to remove future-incompat warning
This fixes warning https://github.com/rust-lang-ci/rust/actions/runs/3477235400/jobs/5813202075#step:25:217
`warning: the following packages contain code that will be rejected by a future version of Rust: ntapi v0.3.7`
by upgrading `sysinfo` version (https://github.com/GuillaumeGomez/sysinfo/blob/master/CHANGELOG.md#0267)
There was some breaking changes in `sysinfo`:
* 0.25.0 (System::refresh_cpu behaviour changed: it only computes CPU usage and doesn't retrieve CPU frequency.) not affected?
* 0.26.0 (Switch memory unit from kilobytes to bytes) fixed.

If clang isn't the C compiler used for the UEFI targets, or if the wrong
`--target` is passed to clang, we will get ELF objects in some
rlibs. This will cause problems at link time when trying to compile a
UEFI program that uses any of those objects. Add a check to the dist
step for UEFI targets that reads each rlib with the `object` crate and
fails with an error if any non-COFF objects are found.

See https://github.com/rust-lang/compiler-team/issues/566.
The motivation for changing the default is to avoid downloading and building LLVM when someone runs `x build` before running `x setup`.
The motivation for only doing it on `channel = "dev"` is to avoid breaking distros or users installing from source. It works because `dev` is also the default channel.
The diff looks larger than it is; most of it is moving the `llvm` branch below the `rust` so `config.channel` is set.

fix sysroot issue which appears for ci downloaded rustc
Currently when compiler is downloaded rather than compiled, sysroot is being `ci-rustc-sysroot` because of https://github.com/rust-lang/rust/blob/7eef946fc0e0eff40e588eab77b09b287accbec3/src/bootstrap/compile.rs#L1125-L1131 this.
And rustdoc is overriding the downloaded one at the end of the process.
With the condition I add, we simply check if the current compiler stage is target build stage, if so use the proper sysroot instead of `ci-rustc-sysroot`.
Resolves #103206

Partial support for running UI tests with `download-rustc`
Right now trying to run UI tests with `download-rustc` results in a bunch of test failures, requiring someone who wants to only work on tests to also build the full compiler. This PR **partially** addresses the problem by solving a lot of the errors (but not all).
* This installs the `rust-src` component on CI toolchains, since the test output depends on whether the standard library source code is installed; We can't just symlink the current source because the `rustc-dev` component already includes the compiler sources, but not the library sources, and mixing things is worse IMO.
* This ensures the `$SRC_DIR` normalization done by compiletest correctly handles the source code added above.
* This unconditionally sets `remap-prefix` to the prefix used in the downloaded toolchain, to ensure compiletest normalizes it.

This also adds a new `mod download` instead of scattering the download code
across `config.rs` and `native.rs`.

Change the way libunwind is linked for *-windows-gnullvm targets
I have no idea why previous way works for `x86_64-fortanix-unknown-sgx` (assuming it actually works...) but not for `gnullvm`. It fails when linking libtest during Rust build (unless somebody adds `RUSTFLAGS='-Clinkarg=-lunwind'`).
Also fixes exception handling on AArch64.

This makes it a lot easier to understand what commands will be run without
having to parse the `-vv` output, which isn't meant to be user facing.

Reduce default configuration's dependency upon static libstdcpp library (#103606)
Fixes #103606
Remove default dependency on static libstdcpp except during dist llvm builds (where we want static libraries so `libLLVM.so` is self-contained).
|
|
Usually, we do want to use the static C++ library when building rustc_llvm, but do not want to have that dependency at compiler runtime. Change the defaults to Make It So.

bootstrap: add support for running Miri on a file
This enables:
```
./x.py run src/tools/miri --stage 0 --args src/tools/miri/tests/pass/hello.rs
```
That can be super helpful for debugging.
Also avoid sharing the Miri sysroot dir with a system-wide (rustup-managed) installation of Miri.

Fix json flag in bootstrap doc
Fix the `--json` flag not working with x.py (Closes #103816)
While this works I'm not sure about the `should_run` of `JsonStd`, had to change it because https://github.com/rust-lang/rust/blob/ab5a2bc7316012ee9b2a4a4f3821673f2677f3d5/src/bootstrap/builder.rs#L334 would match with JsonStd and remove the paths that Std matched. So I did [this](https://github.com/viandoxdev/rust/blob/ffd4078264c4892b5098d6191e0adfe3564d62ca/src/bootstrap/doc.rs#L526-L534) but that looks more like a hack/workaround than anything. I'm guessing there's something to do with the default condition thing but idk how it works

Move browser opening logic in `Builder`
This allows `open()` to be called from other places in bootstrap (I need this for Ferrocene, as we keep our custom steps in `src/bootstrap/ferrocene`), and it simplifies the callers by moving the `was_invoked_explicitly` check into the function.

Fix artifact version/channel detection for stable
On stable, our artifacts are uploaded with the raw version number (e.g., 1.65.0), not the channel. This adjusts our detection logic to use the version number from src/version when we detect the stable channel.
This is really only important for stable channel re-builds, I think, but those do happen from time to time. I'm backporting a similar commit in https://github.com/rust-lang/rust/pull/103859 to make that PR pass CI.
