Windows: Update generated bindings
Update to windows-bindgen 0.59.
This update is aimed at reducing churn in the future, but means a bit more churn now:
- `bindings.txt` no longer needs us to write the namespace for each item. This is good because it means in the future we won't need to change them if the namespace changes. However, there are a few where we still need to disambiguate due to duplicate items (this is a bug in the upstream metadata).
- The output in `windows-sys.rs` is now sorted. It was mostly sorted before but not intentionally. This should mean future changes are less noisy.
The actual code changes are minimal here. A few types are now `bool` instead of `BOOLEAN`, which is more convenient.

add x86-sse2 (32bit) ABI that requires SSE2 target feature
This is the first commit of https://github.com/rust-lang/rust/pull/135408:
The primary goal of this is to make SSE2 required for our i686 targets (at least for the ones that use Pentium 4 as their baseline), to ensure they cannot be affected by https://github.com/rust-lang/rust/issues/114479. This has been MCPd in https://github.com/rust-lang/compiler-team/issues/808, and is tracked in https://github.com/rust-lang/rust/issues/133611.
We do this by defining a new ABI that these targets select, and making SSE2 required by the ABI (that's the first commit). That's kind of a hack, but it is the easiest way to make a target feature required via the target spec. In a follow-up change (https://github.com/rust-lang/rust/pull/135408), we can actually make use of SSE2 for the ABI, but that is running into some infrastructure issues.

Prepare standard library for Rust 2024 migration
This includes a variety of commits preparing the standard library for migration to Rust 2024.
The actual migration is blocked on a few things, so I wanted to get this out of the way in a relatively digestable PR.

Fix presentation of purely "additive" replacement suggestion parts
#127541 changes replacement suggestions to use the "diff" view always, which I think is really verbose in cases where a replacement snippet is a "superset" of the snippet that is being replaced.
Consider:
```
LL - Self::Baz: Clone,
LL + Self::Baz: Clone, T: std::clone::Clone
```
In this code, we suggest replacing `", "` with `", T: std::clone::Clone"`. This is a consequence of how the snippet is constructed. I believe that since the string that is being replaced is a subset of the replacement string, it's not providing much value to present this as a diff. Users should be able to clearly understand what's being suggested here using the `~` underline view we've been suggesting for some time now.
Given that this affects ~100 tests out of the ~1000 UI tests affected, I expect this to be a pretty meaningful improvement of the fallout of #127541.
---
In the last commit, this PR also "trims" replacement parts so that they are turned into their purely additive subset, if possible. See the diff for what this means.

valtree performance tuning
Summary: This PR makes type checking of code with many type-level constants faster.
After https://github.com/rust-lang/rust/pull/136180 was merged, we observed a small perf regression (https://github.com/rust-lang/rust/pull/136318#issuecomment-2635562821). This happened because that PR introduced additional copies in the fast reject code path for consts, which is very hot for certain crates: https://github.com/rust-lang/rust/blob/6c1d960d88dd3755548b3818630acb63fa98187e/compiler/rustc_type_ir/src/fast_reject.rs#L486-L487
This PR improves the performance again by properly interning the valtrees so that copying and comparing them becomes faster. This will become especially useful with `feature(adt_const_params)`, so the fast reject code doesn't have to do a deep compare of the valtrees.
Note that we can't just compare the interned consts themselves in the fast reject, because sometimes `'static` lifetimes in the type are be replaced with inference variables (due to canonicalization) on one side but not the other.
A less invasive alternative that I considered is simply avoiding copies introduced by https://github.com/rust-lang/rust/pull/136180 and comparing the valtrees it in-place (see commit: https://github.com/rust-lang/rust/commit/9e91e50ac5920f0b9b4a3b1e0880c85336ba5c64 / perf results: https://github.com/rust-lang/rust/pull/136593#issuecomment-2642303245), however that was still measurably slower than interning.
There are some minor regressions in secondary benchmarks: These happen due to changes in memory allocations and seem acceptable to me. The crates that make heavy use of valtrees show no significant changes in memory usage.

Rename rustc_middle::Ty::is_unsafe_ptr to is_raw_ptr
The wording unsafe pointer is less common and not mentioned in a lot of places, instead this is usually called a "raw pointer". For the sake of uniformity, we rename this method.

Change swap_nonoverlapping from lang to library UB
The implementation of ptr::swap_nonoverlapping does not always escalate its safety contract to language UB, so it should be `check_library_ub`.

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.

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.

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.
