(cherry picked from commit b791169)
LangItem might eventually be the type that forces us to support `#[derive(StableHash)]` for enums with more than 256 variants.
This commit also removes `#[derive(Hash)]` from the affected types, since it is no longer used. If these types need a plain Hash impl is needed in the future, it could potentially share the `stable_hash_inner` implementation.
By moving away from the old `impl_stable_traits_for_trivial_type!` macro, this commit has the side-effect of removing unused StableOrd impls for some types. Those impls could potentially be re-added if they are ever needed.
Add a test for a case that results in a recursive loop that runs until it runs out of memory or gets killed. This used to take a long time to compile because of nested recursion caused by dereferencing the type of the struct. Signed-off-by: Hardik Kumar <hardikxk@gmail.com>

…rk-Simulacrum Bump stage0 to 1.101.0-beta.1 https://forge.rust-lang.org/release/process.html#default-branch-bootstrap-update-and-crater-tuesday - run replace-version-placeholder (cherry-picked from beta) - bump stage0 to 1.101.0-beta.1 - update STAGE0_MISSING_TARGETS - reformat with `cfg_select!` awareness - update `cfg(bootstrap)`
feat: support nested functions with `#[offload_kernel]` Related to rust-lang#131513. Allows annotating nested functions with `#[offload_kernel]`, similar to autodiff. Also fixes the error message when `#[offload_kernel]` is used on anything other than functions. r? @ZuseZ4 (@Sa4dUs, ping)
Avoid `Hash::hash` when stable-hashing various types This PR makes StableHash independent of stdlib-dependent Hash impls for several types, to avoid potential inconsistency in stable hashing between stage1 and stage2 compilers. This covers all of the StableHash impls that I'm aware of. However, there are still various other places in the compiler where we rely on `Hash::hash` for hashes that probably should be made consistent between compiler stages.

…ns, r=Mark-Simulacrum Avoid redundant scans when extracting stage0 archives [`getnames()`](https://github.com/python/cpython/blob/b4e48a444ea02921ce4b701fe165e6cfd4cf5845/Lib/tarfile.py#L1991-L1995) calls [`getmembers()`](https://github.com/python/cpython/blob/b4e48a444ea02921ce4b701fe165e6cfd4cf5845/Lib/tarfile.py#L1981-L1989), which can scan the entire archive if its members have not already been loaded. Iterating over tar directly (https://github.com/python/cpython/blob/v3.10.12/Lib/tarfile.py#L2715-L2747) allows archive entries to be handled one at a time. Passing each `TarInfo` directly to [`extract()`](https://docs.python.org/3.10/library/tarfile.html#tarfile.TarFile.extract) also avoids name-based lookup, removing the preliminary scan and its associated repeated decompression. With cached stage0 archives, `RustBuild.download_toolchain()` improved from 6.44 s to 3.50 s (medians of two runs per version). The rustc, rust-std, and cargo archives were extracted in parallel into fresh directories. Output hashes were verified separately.
…initions, r=wesleywiser Remove unused compiler modules and types This pr removes unused types and modules. In detail, rust-lang#145244 removed the call to `binary_search_slice`. rust-lang#145951 removed `GenerateProofTree` usages. rust-lang#123761 removed `PrintClosureAsImpl` diagnostic usage in favor of `suggest_impl_trait`. rust-lang#125775 subsequently removed the helper that constructed it.

#165829 flaked out, so instead of letting this run I'm going to make a new rollup of everything. |
