Pass flags to `rustdoc` shim without env. vars
Discussed here: https://github.com/rust-lang/rust/pull/116448#issuecomment-1748785961. Since it was not really documented why these flags were passed through the shim, I guess that the only way to find out if it's really needed... is to remove it :)

Enable Rust to use the EHCont security feature of Windows
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 Guard has already been merged into LLVM, long ago. This change simply adds the Rust codegen option to enable it.
Relevant LLVM change: https://reviews.llvm.org/D40223
This also adds a new `ehcont-guard` option to the bootstrap config which enables EHCont Guard when building std.
We at Microsoft have been using this feature for a significant period of time; we are confident that the LLVM feature, when enabled, generates well-formed code.
We currently enable EHCONT using a codegen feature, but I'm certainly open to refactoring this to be a target feature instead, or to use any appropriate mechanism to enable it.

When building the standard library with Miri, it appears that cargo-miri
does not respect the RUSTFLAGS and even if they did it would be wrong
since they are created for ToolRustc not Std. To avoid errors ignore
RUSTC_HOST_FLAGS for Miri.
Remove i686-apple-darwin cross-testing
The Xcode SDK no longer ships with 32-bit Intel (i686-apple-darwin) support as of [Xcode 14](https://developer.apple.com/news/upcoming-requirements/?id=06062022a) (related, #112753). On an up-to-date Intel Mac, `x.py test --bless` fails.

Explicitly unset $CARGO for compiletest
Some UI tests trigger behavior in rustc where it reads $CARGO and changes behavior if it exists. To make the tests work that rely on it not being set, make sure it is not set.
By default, this is not set, but people may do weird hacks that cause it to be set.

doc: add release notes to standalone doc bundle
Preview: http://notriddle.com/rustdoc-html-demo-5/release-notes/releases.html
This is a workaround for #101714 on top of being a useful addition in its own right. It is intended to change the "canonical URL" for viewing the release notes from GitHub, which is relatively slow, to a pre-rendered HTML file that loads from the same CDN as the standard library docs. It also means you get a copy of the release notes when installing the rust-docs with rustup.

Set `CFG_OMIT_GIT_HASH=1` during builds when `omit-git-hash` is enabled
This environment variable will allow tools like Cargo to disable their own detection when `omit-git-hash` is set to `true`.
I created this PR because of https://github.com/rust-lang/cargo/pull/12968. There is not a dependency between the two PRs, they can land in any order. They just won't do anything until both of them are merged into the repo.
deprecate `if-available` value of `download-ci-llvm`
This PR deprecates the use of the `if-available` value for `download-ci-llvm` since `if-unchanged` serves the same purpose when no changes are detected. In cases where changes are present, it is assumed that compiling LLVM is acceptable (otherwise, why make changes there?).
This was probably missing in the #110087 issue before.

Remove asmjs
Fulfills [MCP 668](https://github.com/rust-lang/compiler-team/issues/668).
`asmjs-unknown-emscripten` does not work as-specified, and lacks essential upstream support for generating asm.js, so it should not exist at all.
bootstrap: simplify setting unstable-options for tools
Previously, we unconditionally(instead of `if path == "src/tools/clippy" || ..`) set this (to prevent recompiling tools between `x check $tool` and '` check $another_tool` executions) specifically for tools in the `x check` step. This PR relocates that logic to `fn prepare_tool_cargo`, making it step-agnostic.
Fixes#116538Fixes#117983
Building rustc with `--rust-profile-use` is currently dumping a lot of
warnings of "no profile data available for function" from `rustc_smir`
and `stable_mir`. These simply aren't exercised by the current profile-
gathering steps, but that's to be expected for new or experimental
functionality. I think for most people, these warnings will be just
noise, so it makes sense to only have them in verbose builds.
This is a workaround for #101714 on top of being a useful addition
in its own right. It is intended to change the "canonical URL"
for viewing the release notes from GitHub, which is relatively
slow, to a pre-rendered HTML file that loads from the same CDN
as the standard library docs. It also means you get a copy of
the release notes when installing the rust-docs with rustup.
We unconditionally set this to avoid recompiling tools between
`x check $tool` and `x test $tool` executions.

As the .last-warned-change-id is only used for change tracking,
we don't need to generate/write it outside of the tty.
Otherwise, rust-analyzer could create this file, and developers
wouldn't be able to see the bootstrap change alerts, assuming
that they have already seen them.

enable unstable feature on `x clean [PATH]`
Since https://github.com/rust-lang/rust/pull/111076 enables unstable cargo feature (`public-dependency`), we need to ensure that unstable features are enabled before reading libstd Cargo.toml.

check config file before prompts on `x setup`
First 2 commit moves the check of configuration existence to the first step of `x setup`. And then followed by a prompt that allows devs to decide whether to continue with the configuration override or exit bootstrap.
Closes#110471
I can revert the last commit if needed. Maybe it's just me, but I feel it's better to have those tags capitalized. If you think otherwise, please let me know so that I can revert.
Allow configuring the parent GitHub repository
The git integration in build_helper hardcoded `rust-lang/rust` as the parent GitHub repository, and `master` as the branch name. This works great for `rust-lang/rust`, but causes problems in downstream forks like Ferrocene whenever those functions are invoked (like `./x fmt`).
In `src/stage0.json` there was already a configuration key for the name of the nightly branch, but it wasn't used by build_helper. This PR adds the `github_repository` key to the file, and requires both values to be passed to build_helper whenever a git function is called. This will allow downstream forks to tweak the values.
Instead of immediately terminating bootstrap, users are now given
the option to decide whether they want to override the file or leave
it unchanged.

Since `x clean` runs with bootstrap, we can speed up
this process by avoiding the cleaning of bootstrap artifacts,
as they are not necessarily needed to be cleaned.

handle the case when the change-id isn't found
When we switch back and forth between the old and recent branches, if there was a breaking change in the bootstrap configuration in between, we have to update the change-id in the build configuration with each checkout, which can be exhausting. This change fixes that.
