Use a single ReentrantMutex implementation on all platforms.
This replaces all platform specific ReentrantMutex implementations by the one I added in #95727 for Linux, since that one does not depend on any platform specific details.

Respect ranlib specified for target during LLVM build
The ranlib specified for the target was never actually transferred
into the builder configuration. In the dist-x86_64-linux build we
ended up using ranlib instead of llvm-ranlib.
Found this investigating a build failure in #94214.
Add support for LibreSSL 3.4.x
This updates the `openssl` and `openssl-sys` crates to support building
the toolchain with system libraries up to LibreSSL 3.4.x.
LibreSSL 3.4.0 has been supported since `openssl-sys` version 0.9.67,
LibreSSL 3.4.x since `openssl-sys` 0.9.72.
Make `x test --stage 2 compiler/rustc_XXX` faster to run
Previously, bootstrap unconditionally rebuilt the stage 2 compiler,
even if it had previously built stage 1. This changes it to reuse stage 1 if possible.
In particular, it no longer runs the following step:
```
Building stage1 compiler artifacts (x86_64-unknown-linux-gnu(x86_64-unknown-linux-gnu) -> x86_64-unknown-linux-gnu(x86_64-unknown-linux-gnu))
```
Add codegen tests for additional cases where noop iterators get optimized away
Optimizations have improved over time and now LLVM manages to optimize more in-place-collect noop-iterators to O(1) functions. This updates the codegen test to match.
Many but not all cases reported in #79308 work now.
fix error handling for pthread_sigmask(3)
Errors from `pthread_sigmask(3)` were handled using `cvt()`, which expects a return value of `-1` on error and uses `errno`.
However, `pthread_sigmask(3)` returns `0` on success and an error number otherwise.
Fix it by replacing `cvt()` with `cvt_nz()`.
Fix rustdoc duplicated blanket impls
Fixes#96036.
I think it'll not be great performance-wise but I couldn't find another way to prevent that unfortunately...

The main branch of Cranelift has switched to a new register allocator.
This register allocator doesn't have any alternative regalloc algorithms
unlike the old register allocator.
Report undeclared lifetimes during late resolution.
First step in https://github.com/rust-lang/rust/pull/91557
We reuse the rib design of the current resolution framework. Specific `LifetimeRib` and `LifetimeRibKind` types are introduced. The most important variant is `LifetimeRibKind::Generics`, which happens each time we encounter something which may introduce generic lifetime parameters. It can be an item or a `for<...>` binder. The `LifetimeBinderKind` specifies how this rib behaves with respect to in-band lifetimes.

Remove last vestiges of skippng ident span hashing
This removes a comment that no longer applies, and properly hashes
the full ident for path segments.
Refactor HIR item-like traversal (part 1)
Issue #95004
- Create hir_crate_items query which traverses tcx.hir_crate(()).owners to return a hir::ModuleItems
- use tcx.hir_crate_items in tcx.hir().items() to return an iterator of hir::ItemId
- use tcx.hir_crate_items to introduce a tcx.hir().par_items(impl Fn(hir::ItemId)) to traverse all items in parallel;
