Rollup merge of #123642 - onur-ozkan:restrict-llvm-option, r=Mark-Simulacrum
do not allow using local llvm while using rustc from ci

From: https://github.com/rust-lang/rust/issues/123586#issuecomment-2043296578

> Even if `llvm.download-ci-llvm` is set to true, `stage > 0` rustc will always use the prebuilt LLVM library which comes with ci-rustc. So I tried to use locally-built LLVM libraries in the ci-rustc by replacing the existing LLVM libraries with the locally built ones, and it appears that this is indeed a limitation of using `rust.download-rustc=true` as it fails with the following error:
>
> ```
> $ ./build/host/ci-rustc/bin/rustc --version
> ./build/host/ci-rustc/bin/rustc: symbol lookup error: /home/nimda/devspace/.other/rustc-builds/build/x86_64-unknown-linux-gnu/ci-rustc/bin/../lib/librustc_driver-a03ea465d8e03db1.so: undefined symbol: LLVMInitializeARMTargetInfo, version LLVM_18.1
> ```
>
> So, if `rust.download-rustc` is set to true and `llvm.download-ci-llvm` is false, I believe bootstrap should terminate the process (as it always uses prebuilt LLVM libraries from ci-rustc, there is no point to build LLVM locally) while parsing the configuration.

onur-ozkan bd479113d3 correct the handling of `bootstrap-cache-path` option
This change makes `build.bootstrap-cache-path` option to be configurable with
`./configure` script, so it can be used like `./configure --bootstrap-cache-path=demo`.

Alex Crichton dd95cb7106 Add `target.*.runner` configuration for targets
This commit adds a `runner` field configuration to `config.toml` for
specifying a wrapper executable when executing binaries for a target.
This is pulled out of #122036 where a WebAssembly runtime is used, for
example, to execute tests for `wasm32-wasip1`.

The name "runner" here is chosen to match Cargo's `CARGO_*_RUNNER`
configuration, and to make things a bit more consistent this
additionally renames compiletest's `--runtool` argument to `--runner`.

Alex Crichton cb39d6c515 Add a new `wasm32-wasip1` target to rustc
This commit adds a new target called `wasm32-wasip1` to rustc.
This new target is explained in these two MCPs:

* https://github.com/rust-lang/compiler-team/issues/607
* https://github.com/rust-lang/compiler-team/issues/695

In short, the previous `wasm32-wasi` target is going to be renamed to
`wasm32-wasip1` to better live alongside the [new
`wasm32-wasip2` target](https://github.com/rust-lang/rust/pull/119616).
This new target is added alongside the `wasm32-wasi` target and has the
exact same definition as the previous target. This PR is effectively a
rename of `wasm32-wasi` to `wasm32-wasip1`. Note, however, that
as explained in rust-lang/compiler-team#695 the previous `wasm32-wasi`
target is not being removed at this time. This change will reach stable
Rust before even a warning about the rename will be printed. At this
time this change is just the start where a new target is introduced and
users can start migrating if they support only Nightly for example.

bjorn3 28af00c611 Support configuring the set of codegen backends to build per host triple
This allows building the compiler itself with one backend while using
another backend at runtime. For example this allows compiling rustc to
wasm using LLVM, while using Cranelift at runtime to produce actual
code. Cranelift can't compile to wasm, but is perfectly capable of
running on wasm. LLVM can compile to wasm, but can't run on wasm. [^1]

[^1]: The prototype of this still requires a couple of other patches.

jyn 6a409ddbe4 add a new `optimized_compiler_builtins` option
in particular, this makes the `c` feature for compiler-builtins an explicit opt-in, rather than silently detected by whether `llvm-project` is checked out on disk.
exposing this is necessary because the `cc` crate doesn't support cross-compiling to MSVC, and we want people to be able to run `x check --target foo` regardless of whether they have a c toolchain available.

this also uses the new option in CI, where we *do* want to optimize compiler_builtins.

the new option is off by default for the `dev` channel and on otherwise.

Arlie Davis e11d8d147b Add support for generating the EHCont section
In the future Windows will enable Control-flow Enforcement Technology
(CET aka Shadow Stacks). To protect the path where the context is
updated during exception handling, the binary is required to enumerate
valid unwind entrypoints in a dedicated section which is validated when
the context is being set during exception handling.

The required support for EHCONT has already been merged into LLVM,
long ago. This change adds the Rust codegen option to enable it.

Reference:

* https://reviews.llvm.org/D40223

This also adds a new `ehcont-guard` option to the bootstrap config which
enables EHCont Guard when building std.

Peter Collingbourne aad44b3b54 Improve android-ndk property interface
PR #105716 added support for NDK r25b, and removed support for r15. Since
the switch to r25b would have broken existing r15 users anyway, let's
take the opportunity to make the interface more user friendly.

Firstly move the android-ndk property to [build] instead of the
targets. This is possible now that the NDK has obsoleted the concept of
target-specific toolchains.

Also make the property take the NDK root directory instead of the
"toolchains/llvm/prebuilt/<host tag>" subdirectory.

bootstrap major change detection implementation

The use of `changelog-seen` and `bootstrap/CHANGELOG.md` has not been functional in any way for many years. We often do major/breaking changes but never update the changelog file or the `changelog-seen`. This is an alternative method for tracking major or breaking changes and informing developers when such changes occur.

Example output when bootstrap detects a major change:

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.

Documentations:
ISA:
https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html
ABI:
https://loongson.github.io/LoongArch-Documentation/LoongArch-ELF-ABI-EN.html
More docs can be found at:
https://loongson.github.io/LoongArch-Documentation/README-EN.html

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
