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.
r? bootstrap
Removed dependency on the field-offset crate, alternate approach
This is an alternate approach to reach the same goals as #136003. As it touches the core of the query system, this too probably should be evaluated for performance.
r? ``@Mark-Simulacrum``
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.

compiler: mostly-finish `rustc_abi` updates
This almost-finishes all the updates in the compiler to use `rustc_abi` and removes some of the reexports of `rustc_abi` items in `rustc_target` that were previously available.

Make empty-line-after an early clippy lint
r? ```@y21```
95% a refiling of https://github.com/rust-lang/rust-clippy/pull/13658 but for correctness it needed 2 extra methods in `rust_lint` which made it much easier to apply on `rust-lang/rust` than `rust-lang/rust-clippy`.
Commits have been thoroughly reviewed on `rust-lang/clippy already`. The last two review comments there (about using `Option` and popping for assoc items have been applied here.
Remove some unnecessary parens in `assert!` conditions
While working on #122661, some of these started triggering our "unnecessary parens" lints due to a change in the `assert!` desugaring. A cursory search identified a few more. Some of these have been carried from before 1.0, were a bulk rename from the previous name of `assert!` left them in that state. I went and removed as many of these unnecessary parens as possible in order to have fewer annoyances in the future if we make the lint smarter.
