Pull some tuple variant fields out into their own struct
This is groundwork for adding more fields to those new structs, but I believe the change to be useful on its own.
r? `@Nilstrieb` but feel free to reroll for `compiler`
Remove `intercrate` and `mark_ambiguous` from `TypeRelation`
Fixes#109863
Pulls this logic into `super_combine_tys`, which has access to `InferCtxt` and takes a `ObligationEmittingRelation` -- both of which simplify the logic here.

Remove optimal xz settings from CI
This is a companion PR to rust-lang/promote-release#58, which moves the relevant optimal code to rust-lang/promote-release. As mentioned in the comments of that PR, this is expected to cut CI costs (and time, though predominantly felt on fast builders) and reduce wasted resources due to in-practice single-threaded compression not using the full 8+ vCPU builders we have available.
This probably shouldn't land before that PR + a simpleinfra change to enable the recompression of xz artifacts. But if it does land, it's just a matter of a few nightlies with slightly larger artifacts, so not a big deal.

rustdoc: make intra-doc link pass non-quadratic for repeated links
In the collect_intra_doc_links pass, links to a given item that occurred repeatedly were getting inserted into a `Vec<clean::ItemLink>` repeatedly. This led to n^2 behavior (where n = the number of pages generated), particularly for the intra-doc link on the `Into<U> for T where U: From<T>` blanket implementation, since that link appears on every single struct page.
Fixes#109851
Never consider int and float vars for `FnPtr` candidates
This solves a regression where `0.0.cmp()` was ambiguous when a custom trait with a `cmp` method was in scope.
For integers it shouldn't be a problem in practice so I wasn't able to add a test.
I'm not sure whether there could be more issues hidden in the shadows as mentioned in the issue, but this should at least fix the problematic regression immediately.

Update contributing links for rustc-dev-guide changes
Companion PR to https://github.com/rust-lang/rustc-dev-guide/pull/1653.
- Remove unused reference link in CONTRIBUTING.md
- Change the contributing_url for triagebot to the getting started page
Increase libffi version to 3.2 to support s390x
libffi versions prior to 3.2 have no support for s390x, causing the Miri build to fail on our platform.
Use `&IndexSlice` instead of `&IndexVec` where possible
All the same reasons as for `[T]`: more general, less pointer chasing, and `&mut IndexSlice` emphasizes that it doesn't change *length*.

Update compiler-builtins to 0.1.91 to bring in msp430 shift primitive…
… fixes.
This fixes unsoundness on MSP430 where `compiler-builtins` and LLVM didn't agree on the width of the shift amount argument of the shifting primitives (4 bytes vs 2 bytes). See https://github.com/rust-lang/compiler-builtins/pull/522 for more details.

binary_heap: Optimize Extend implementation.
This PR makes the `Extend` implementation for `BinaryHeap` no longer rely on specialization, so that it always use the bulk rebuild optimization that was previously only available for the `Vec` specialization.
Include invocation start times
For multi-invocation builders (e.g., dist-x86_64-linux) this timestamp is necessary to correlate the data in the metrics JSON with other data sources (e.g., logs, cpu-usage CSV, etc.). Such correlation may not be perfect but is sometimes helpful and awkward to do otherwise.
fix `build --stage 2 compiler/rustc` panic
Skip assembling(which causes panic due to not found `.librustc.stamp` file) process
