Re-add help_on_error for download-ci-llvm
Closes#97503
- Re-added `help_on_error` for `download_component()` and the downstream functions
- Removed dead code in `bootstrap.py`
Thanks `@jyn514` for the helpful tips!
(first contribution here, please let me know if I missed anything out!)
Finish bumping stage0
It looks like the last time had left some remaining cfg's -- which made me think
that the stage0 bump was actually successful. This brings us to a released 1.62
beta though.
This now brings us to cfg-clean, with the exception of check-cfg-features in bootstrap;
I'd prefer to leave that for a separate PR at this time since it's likely to be more tricky.

Prepare Rust for opaque pointers
Fix one codegen bug with opaque pointers, and update our IR tests to accept both typed pointer and opaque pointer IR. This is a bit annoying, but unavoidable if we want decent test coverage on both LLVM 14 and LLVM 15.
This prepares Rust for when LLVM will enable opaque pointers by default.
Move download-rustc from python to rustbuild
- Remove download-rustc handling from bootstrap.py
- Allow a custom `pattern` in `builder.unpack()`
- Only download rustc once another part of bootstrap depends on it.
This is somewhat necessary since the download functions rely on having a full
`Builder`, which isn't available until after config parsing finishes.
Helps with https://github.com/rust-lang/rust/issues/94829.
[bootstrap] Move `sanitize_sh` from `dist` to `install`
This is the only place it's used, so there's no need for it to be public in another module.
In general, `dist` shouldn't ever touch shell scripts.
Print stderr consistently
Solves https://github.com/rust-lang/rust/issues/96712
I tried to follow what I perceived as the general consensus for error messages in boostrap i.e messages that were ..
* resulting from an Err(...) =>
* literally called as "Error: ...."
* by the end of the block scope forced to run a panic! or process::exit with a guaranteed non-zero error code.

Only allow `compiletest` to use `feature(test)`, not any other feature
Using language features occasionally causes issues when using nightly to bootstrap, rather than beta.
See #59264 for additional context.

- The logic is now unified for all targets (wasm targets should also be supported now)
- Additional "symlink" files like `ld64` are eliminated
- lld-wrapper is used for propagating the correct lld flavor
- Cleanup "unwrap or exit" logic in lld-wrapper
Turn on `fast_submodules` unconditionally
I don't know why anyone would turn this off; doing so makes builds much slower (nearly a 60x slowdown according to #49057).
Remove the option to do so, which makes bootstrap a little easier to maintain.
Bootstrap continues to allow you to manage submodules manually by setting `submodules = false`.

Avoid accidentally enabling unstable features in compilers (take 2)
This allows rustbuild to control whether crates can use nightly features or not.
It also prevents rustbuild from using nightly features itself.
This is #92261, but I fixed the CI error.
Omit stdarch workspace from rust-src
The path `library/stdarch/crates/Cargo.toml` does not exist.
In Rust 1.61.0, `rust-src` still includes `src/rust/library/stdarch/Cargo.toml` (but not `stdarch-verify`), which includes
```toml
[workspace]
members = [
"crates/stdarch-verify"
```
This didn't show up when testing with `-Zbuild-std` in https://github.com/rust-lang/rust/pull/94907 since the [standard list of crates](f624095e1c/src/cargo/core/compiler/standard_lib.rs (L26-L30)) to include when building `std` does not include `stdarch`, but it will show up if a user explicitly requests `stdarch`. Or, perhaps more importantly, because of https://github.com/rust-lang/rust/issues/95736, many editors (like IntelliJ) won't treat the root of `rust-src` as a workspace, and will instead recurse into all the sub-crates directly, which then includes `stdarch`.

Fix `download-ci-llvm` NixOS patching for `.so`s.
See https://github.com/rust-lang/rust/pull/95170#discussion_r872960686 - in short, `Path::ends_with` doesn't do the same thing as `str::ends_with`, and can only be used to check for whole file names, not extensions.

Add compiletest and bootstrap "--skip" option forwarded to libtest
With this PR, "x.py test --skip SKIP ..." will run the specified test suite, but forward "--skip SKIP" to the test tool. libtest already supports this option. The PR also adds it to compiletest which itself just forwards it to libtest.
Adds the functionality requested in https://github.com/rust-lang/rust/issues/96342. This is useful to work around tests broken upstream.
https://github.com/rust-lang/rust/issues/96362#issuecomment-1108609893 is the specific test issue my project is trying to work around.
Fix running bootstrap tests on a fresh clone
In #96303, I changed the tests not to manage submodules, with the main
goal of avoiding a clone for llvm-project. Unfortunately, there are some tests
which depend on submodules - I didn't notice locally because they were already checked out for me,
and CI doesn't use submodule handling at all. Fresh clones, however, were impacted:
```
failures:
---- builder::tests::defaults::doc_default stdout ----
thread 'main' panicked at 'fs::read_dir(builder.src.join(&relative_path).join("redirects")) failed with No such file or directory (os error 2)', src/bootstrap/doc.rs:232:21
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
---- builder::tests::dist::dist_only_cross_host stdout ----
thread 'main' panicked at 'fs::read_to_string(&toml_file_name) failed with No such file or directory (os error 2)', src/bootstrap/lib.rs:1314:20
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
Try and get the best of both worlds by only checking out the submodules actually used in tests.

libtest already supports a "--skip SUBSTRING" arg which excludes any
test names matching SUBSTRING.
This adds a "--skip" argument to compiletest and bootstrap which is
forwarded to libtest.
