use cc archiver as default in `cc2ar`
We should remove entire `cc2ar` but `cc` doesn't seem to cover all the conditions that `cc2ar` handles. For now, I replaced the `else` logic only, which is a bit hacky and unstable.
Fixes #136759

add docs and ut for bootstrap util cache
This PR adds doc and unit test for bootstrap utils/cache module
|

(S)ccache can be useful for more things that just LLVM. For example, we will soon want to use it also for GCC, and theoretically also for building stage0 Rust tools.

improve host/cross target checking
Using an invalid equality operator on `builder.config.build !=/==` can be hard to detect in reviews (which is quite dangerous). Replaced them with `is_host_target`, which is much clearer as it explicitly states what it does.

Only apply LTO to rustdoc at stage 2
It doesn't make much sense at stage 1, and it was broken anyway. This was implemented in https://github.com/rust-lang/rust/pull/135832. The issue with LTO and stage 1 rustdoc was reported [here](https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/x.20test.20with.20lto.20.3D.20.22thin.22.20fails.20to.20build.20rustdoc.3F).

Always set the deployment target when building std
`cc` has [a bug/feature](https://github.com/rust-lang/cc-rs/issues/1171) (I guess depending on how you look at it) where the default deployment target is taken from the SDK instead of from `rustc`. This causes `compiler-builtins` to build `compiler-rt` with the wrong deployment target on iOS.
I've been meaning to change how `cc` works in this regard, but that's a lengthy process, so let's fix it in bootstrap for now.
The behaviour can be seen locally with `./x build library --set build.optimized-compiler-builtins=true` for various target triples, and then inspecting with `otool -l build/host/stage1/lib/rustlib/*/lib/libcompiler_builtins-*.rlib | rg 'minos|version'`. I have added a rmake test that ensures that we now have the same version everywhere.

adding autodiff tests
I'd like to get started with upstreaming some tests, even though I'm still waiting for an answer on how to best integrate the enzyme pass. Can we therefore temporarily support the -Z llvm-plugins here without too much effort? And in that case, how would that work? I saw you can do remapping, e.g. `rust-src-base`, but I don't think that will give me the path to libEnzyme.so. Do you have another suggestion?
Other than that this test simply checks that the derivative of `x*x` is `2.0 * x`, which in this case is computed as
`%0 = fadd fast double %x.0.val, %x.0.val`
(I'll add a few more tests and move it to an autodiff folder if we can use the -Z flag)
r? ``@jieyouxu``
Locally at least `-Zllvm-plugins=${PWD}/build/x86_64-unknown-linux-gnu/enzyme/build/Enzyme/libEnzyme-19.so` seems to work if I copy the command I get from x.py test and run it manually. However, running x.py test itself fails.

[`compiletest`-related cleanups 2/7] Feed stage number to compiletest directly
Reference for overall changes: https://github.com/rust-lang/rust/pull/136437
Part **2** of **7** of the *`compiletest`-related cleanups* PR series.
### Summary
- Pass stage number via new `--stage` compiletest flag directly from bootstrap, instead of deriving that info in compiletest by doing gymnastics on `--stage-id`.
- Just a cleanup, should have no functional changes.

Add amdgpu target
Add amdgpu target to rustc and enable the LLVM target.
Fix compiling `core` with the amdgpu:
The amdgpu backend makes heavy use of different address spaces. This
leads to situations, where a pointer in one addrspace needs to be casted
to a pointer in a different addrspace. `bitcast` is invalid for this
case, `addrspacecast` needs to be used.
Fix compilation failures that created bitcasts for such cases by
creating pointer casts (which creates an `addrspacecast` under the hood)
instead.
MCP: https://github.com/rust-lang/compiler-team/issues/823
Tracking issue: #135024
Kinda related to the original amdgpu tracking issue #51575 (though that one has been closed for a while).

Update bootstrap compiler and rustfmt
The rustfmt version we previously used formats things differently from what the latest nightly rustfmt does. This causes issues for subtrees that get formatted both in-tree and in their own repo. Updating the rustfmt used in-tree solves those issues. Also bumped the bootstrap compiler as the stage0 update command always updates both at the same
time.

Implement `x perf` directly in bootstrap
Discussed [here](https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/Turning.20.60x.20perf.60.20into.20a.20first.20class.20command).
Implementing the command directly in bootstrap let's us correctly build the compiler toolchain based on input arguments (such as include rustdoc in the toolchain [only] when needed), and it also makes the CLI interface nicer.

bootstrap: add wrapper macros for `feature = "tracing"`-gated `tracing` macros
Follow-up to https://github.com/rust-lang/rust/pull/136091#discussion_r1930219425.
- Add wrapper macros for `error!`, `warn!`, `info!`, `debug!` and `trace!`, which `cfg(feature = "tracing")`-gates the underlying `tracing` macros. They expand to nothing if `"tracing"` feature is not enabled.
- This is not done for `span!` or `event!` because they can return span guards, and you can't really wrap that.
- This is also not possible for `tracing::instrument` attribute proc-macro unless you use another attribute proc-macro to wrap that.
It's not *great*, because `tracing::instrument` and `tracing::{span,event}` can't be wrapped this way.
Can test locally with:
```bash
$ BOOTSTRAP_TRACING=bootstrap=TRACE ./x check src/bootstrap/
```

bootstrap: only build `crt{begin,end}.o` when compiling to MUSL
only MUSL needs those objects and trying to compile them to other targets, e.g. Windows or macOS, will produce C compilation errors
check the target before shelling out to the C compiler and tweak `make_run` to skip the actual C compilation when the target is not MUSL
