Sync rustc_codegen_cranelift
The main highlight this sync is the removal of several dependencies, making compilation of cg_clif itself faster. There have also been a couple of new features like `#[link_section]` now supporting different segments for Mach-O binaries (thanks `@eggyal!)` and the `imported_main` feature, which is currently unstable.

We do not install Zlib on the CI but recent builds somehow started picking it's shared version.
To avoid relying on CI binaries so let's explicitly disable it.
In particular the `is_dir`, `is_file` and `exists` functions says that querying a file requires querying the directory. On Windows this is not normally true.
Mention workaround for floats in Iterator::{min, max}
`Iterator::{min, max}` can't be used with iterators of floats due to NaN issues. This suggests a workaround in the documentation of those functions.
Fix trait methods' toggle
A `<details>` tag wasn't closed on trait methods, which created broken DOM. I also used this occasion to only generate the toggle in case there is documentation on the method.
r? `@jsha`
Forwarding `clone_from` to the inner value changes the observable
behavior, as previously the inner value would *not* be dropped by the
default implementation.
Move mini-macro to tests/ui/auxilary
changelog: none
Merges `/mini-macro` into `/tests/ui/auxilary/proc_macro_derive.rs`.
The mini-macro crate is an artifact of the distant past. A lot has changed (#2284) and it doesn't make sense as a top-level crate anymore. Especially since we can use the auxilary folder to accompolish the same thing.
Enable Vec's calloc optimization for Option<NonZero>
Someone on discord noticed that `vec![None::<NonZeroU32>; N]` wasn't getting the optimization, so here's a PR 🙃
We can certainly do this in the standard library because we know for sure this is ok, but I think it's also a necessary consequence of documented guarantees like those in https://doc.rust-lang.org/std/option/#representation and https://doc.rust-lang.org/core/num/struct.NonZeroU32.html
It feels weird to do this without adding a test, but I wasn't sure where that would belong. Is it worth adding codegen tests for these?
Fix missing_docs_in_private_items false negative
changelog: Fix [`missing_docs_in_private_items`] false negative when the item has any `#[name = "value"]` attribute
Closes#7247 (decided not to use the rustc method since it calls `Session::check_name`, which is for rustc only)
Fix allow on some statement lints
changelog: Fix `#[allow(..)]` over statements for [`needless_collect`], [`short_circuit_statement`] and [`unnecessary_operation`]
Fixes#7171Fixes#7202
Add avoid_breaking_exported_api config option
changelog: Add `avoid_breaking_exported_api` config option for [`enum_variant_names`], [`large_types_passed_by_value`], [`trivially_copy_pass_by_ref`], [`unnecessary_wraps`], [`upper_case_acronyms`] and [`wrong_self_convention`].
changelog: Deprecates [`pub_enum_variant_names`] and [`wrong_pub_self_convention`] as the non-pub variants are now configurable.
changelog: Fix various false negatives for `pub` items that are not exported from the crate.
A couple changes to late passes in order to use `cx.access_levels.is_exported` rather than `item.vis.kind.is_pub`.
I'm not sure how to better document the config option or lints that are (not) affected (see comments in #6806). Suggestions are welcome. cc `@rust-lang/clippy`
I added `/clippy.toml` to use the config internally and `/tests/clippy.toml` to maintain a default config in ui tests.
