Stabilize `-Zgcc-ld=lld` as `-Clink-self-contained=linker -Clinker-flavor=gcc-lld`

# Proposal In the context of improvements to compile-times, we'd like to make progress on [enabling LLD by default](https://github.com/rust-lang/rust/issues/39915). Since this is a broad topic, with known issues and multiple...

Opening an issue as requested by @Mark-Simulacrum : While launching a run on a limited selection of crates [on this PR](https://github.com/rust-lang/rust/pull/73905#issuecomment-674532428) using the `crates=list:link` format [documented here](https://github.com/rust-lang/crater/blob/master/docs/bot-usage.md#available-crate-selections), the bot returned...

Error about non-existing file that exists

### Problem There may be new settings and default values that could improve compile times for build dependencies. ### Proposed Solution In particular, turning off debuginfo, and to a lesser...

Bisect through rollups using perf.rlo's individual PR artifacts

4

Recently, support was added to the perfbot to build the artifacts of all the PRs in a rollup. For example, [here](https://github.com/rust-lang/rust/pull/100048#issuecomment-1202205306) we can see each sha1 artifact that was built....

This is not really an issue per se, but apart from https://github.com/bjorn3/rustc_codegen_cranelift/issues/1090 there was no mention of it. From reading https://www.reddit.com/r/rust/comments/15drwt8/progress_report_on_rustc_codegen_cranelift_july/ it seems people don't know they can sponsor you/this...

Build `rustc` with 1CGU on `x86_64-apple-darwin`

29

Distribute `x86_64-apple-darwin` artifacts built with `rust.codegen-units=1`, like we already do on Linux. 1) effect on code size on `x86_64-apple-darwin`: it's a 11.14% reduction on `librustc_driver.dylib` - before, [`41d97c8a5dea2731b0e56fe97cd7cb79e21cff79`](https://ci-artifacts.rust-lang.org/rustc-builds/41d97c8a5dea2731b0e56fe97cd7cb79e21cff79/rustc-nightly-x86_64-apple-darwin.tar.xz): 161232048 -...

This PR is the companion announcement post needed for https://github.com/rust-lang/rust/pull/124129, about switching the default linker on linux nightlies to `rust-lld`, our "self-contained `lld`". The publication date is just a random...

It could be interesting to have simple statistics, for example behind a feature flag, of the number of tuples and the time it took to merge and create them, for...
