Before, you could have the confusing situation where the command to
generate a component had no relation to the name of that component (e.g.
the `rustc` component was generated with `src/librustc`). This changes
the name to make them match up.
Skip documentation for tier 2 targets on dist-x86_64-apple-darwin
I don't have an easy way to test this locally, but I believe it should work. Based on one log result should shave ~14 minutes off the dist-x86_64-apple builder (doesn't help with aarch64 dist or x86_64 test builder, so not actually decreasing total CI time most likely).

CI: Enable overflow checks for test (non-dist) builds
They stay disabled for Apple builds though, which take the most time already due to running on slow hw.
Build aarch64-apple-ios-sim as part of the full macOS build
Part of the [MCP 428](https://github.com/rust-lang/compiler-team/issues/428) to promote this target to Tier 2.
This adds the aarch64-apple-ios-sim target as a tier 2 target, currently cross-compiled from our x86_64 apple builders. The compiler team has approved the addition per the MCP noted above, and the infrastructure team has not raised concerns with this addition at this time (as the CI time impact is expected to be minimal; this is only building std).
During the 1.52 release process we had to deal with some commits that
passed the test suite on the nightly branch but failed on the beta or
stable branch. In that case it was due to some UI tests including the
channel name in the output, but other changes might also be dependent on
the channel.
This commit adds a new CI job that runs the Linux x86_64 test suite with
the stable branch, ensuring nightly changes also work as stable.
Demote i686-unknown-freebsd to tier 2 compiler target
While technically the `i686-unknown-freebsd` target has been a tier 2 development platform for a long time, with full toolchain tarballs available on static.rust-lang.org, due to a bug in the manifest generation the target was never available for download through rustup.
The infrastructure team privately inquired the FreeBSD package maintainers, and they weren't relying on those tarballs either, so it's a fair assumption to say practically nobody is using those tarballs.
This PR then removes the CI builder that produces full tarballs for the target, and moves the compilation of `rust-std` for the target in `dist-various-2`. The `x86_64-unknown-freebsd` target is *not* affected.

Promote aarch64-unknown-linux-gnu to Tier 1
This PR promotes the `aarch64-unknown-linux-gnu` target to Tier 1, as proposed by [RFC 2959]:
* The `aarch64-gnu` CI job is moved from `auto-fallible` to `auto`.
* The platform support documentation is updated, uplifting the target to Tiert 1 with a note about missing stack probes support.
* Building the documentation is enabled for the target, as we produce the `rust-docs` component for all Tier 1 platforms.

Historically we've disabled these assertions on a number of platforms with the
goal of speeding up CI. Now, though, having migrated to GitHub actions, CI is
already pretty fast, and these debug assertions do bring us some value.
This does leave in some debug assertions that are performance-related: macOS
currently hovers at just under 2 hours.
There are also some other builders which have debug and LLVM assertions
disabled:
llvm-8, PR builder:
In one view, this builder tests our support for older LLVMs. But in reality, a
lot of our tests already disable themselves on older LLVMs, and I think our
general stance is that we really only support the in-tree LLVM. Plus, we really
want CI times on this builder to be really low, as it's run on *every* PR --
that's a lot of CI time.
test-various:
This disables debug asserts still -- as noted in the Dockerfile, we test code
size, and we need debug asserts off for that to work well.
This was recommended by GitHub Support to try reducing the things that
could've caused #78743. I checked the changelog and there should be no
practical impact for us (we already set an explicit fetch-depth).

Promote aarch64-pc-windows-msvc to Tier 2 Development Platform
Adds a GitHub Actions CI build for `aarch64-pc-windows-msvc` via cross-compilation on an x86_64 host.
This promotes `aarch64-pc-windows-msvc` from a Tier 2 Compilation Target (std) to a Tier 2 Development Platform (std+rustc+cargo+tools).

Set ninja=true by default
Ninja substantially improves LLVM build time. On a 96-way system, using
Make took 248s, and using Ninja took 161s, a 35% improvement.
We already require a variety of tools to build Rust. If someone wants to
build without Ninja (for instance, to minimize the set of packages
required to bootstrap a new target), they can easily set `ninja=false`
in `config.toml`. Our defaults should help people build Rust (and LLVM)
faster, to speed up development.
The purpose of the auto-fallible job is to run builders that are likely
to fail on CI without gating on them. Having fail-fast enabled there
kinda defeats the purpose, as if one of them fails we can't monitor the
outcome of the other ones.
This was prompted by the aarch64-gnu builder consistently failing due to
a broken test, preventing us from seeing if the macOS spurious failure
is fixed.
Add fallible AArch64 CI builder
This adds the `aarch64-gnu` CI builder to the `auto-fallible` job, as a first step in the process of actually gating on it.
