Clarify the meaning of `AttributeOrder::KeepFirst` and `AttributeOrder::KeepLast`
Clarify the meaning of `KeepLast` and `KeepFirst` for https://github.com/rust-lang/rust/issues/131229#issuecomment-2971353197
Just a minor clarification, but me and ``@JonathanBrouwer`` have confused these two a few times so I think it's warranted.

Update intro blurb in `wasm32-wasip1` docs
I was reading over this documentation in light of the effort to enlist more maintainers for Tier 2 targets and figured it was time for a refresh of this documentation now that historical renames/etc have all become a thing of the past. No new major changes to this documentation, mostly just wanted to update it and reflect the modern status quo for this target.
Don't mark `#[target_feature]` safe fns as unsafe in rustdoc JSON.
Fixes https://github.com/rust-lang/rust/issues/142655 by explicitly checking whether functions are safe but using `#[target_feature]`, instead of relying on the `FnHeader::is_unsafe()` method which considers such functions unsafe.
I don't believe this merits a bump of the rustdoc JSON `FORMAT_VERSION` constant, since the format is unchanged and this is just a small bugfix.

changelog: [`exit`]: When using the `--test` or `--all-targets` flag,
the exit lint should not fail on the main function.

With help from @sesgoe
Now that `#[used(linker)]` is the default on ELF, we don't need to use the
`-znostart-stop-gc` link-arg workaround to match bfd's behavior when
using lld.
- update existing tests for stabilization
- ensure `-Clink-self-contained=-linker` is only stable on x64 linux
- test invalid `-Clink-self-contained` components
That step should be responsible for building the tool, not performing side-effects. Also, only copy the tool to the `self-contained` directory, not to the `rustlib/<target>/bin` directory.
This stabilizes a subset of the `-Clink-self-contained` components on x64 linux:
the rust-lld opt-out.
The opt-in is not stabilized, as interactions with other stable flags require
more internal work, but are not needed for stabilizing using rust-lld by default.
Similarly, since we only switch to rust-lld on x64 linux, the opt-out is
only stabilized there. Other targets still require `-Zunstable-options`
to use it.

See RUST-141600: this test is broken in two ways:
1. This test triggers `-Wincompatible-pointer-types` on GCC 14.
2. This test requires ARMv8.5+ w/ MTE extensions enabled, but GHA CI
runner hardware do not have this enabled.
