bump few ICU4X leftover deps
implements https://github.com/rust-lang/rust/pull/117632#issuecomment-1795027801 suggestion
There no strict version dependencies between some crates, so yoke was 0.7.2, but yoke-derive left with 0.7.1, same with zerofrom, zerofrom-derive, zerovec, zerovec-derive; drops synstructure 0.12* dependency, less syn 1.* users left.

Allow configuring the parent GitHub repository
The git integration in build_helper hardcoded `rust-lang/rust` as the parent GitHub repository, and `master` as the branch name. This works great for `rust-lang/rust`, but causes problems in downstream forks like Ferrocene whenever those functions are invoked (like `./x fmt`).
In `src/stage0.json` there was already a configuration key for the name of the nightly branch, but it wasn't used by build_helper. This PR adds the `github_repository` key to the file, and requires both values to be passed to build_helper whenever a git function is called. This will allow downstream forks to tweak the values.

Update ICU4X
This updates all ICU4X crates and regenerates rustc_baked_icu_data.
Since the new unicode license under which they are licensed does not have an SPDX identifier yet, we define some exceptions. The license has to be reviewed to make sure it is still fine to use here, but I assume that is the case.
I also added an exception for rustc_icu_data to the unexplained ignore doctest tidy lint. This is a bit hacky but the whole style.rs in tidy is a mess so I didn't want to touch it more than this small hack.

coverage: Rename the `run-coverage` test mode to `coverage-run`
Follow-up to https://github.com/rust-lang/rust/pull/117484#issuecomment-1788916563.
Renaming this test mode to `coverage-run` makes it more consistent with the `coverage-map` mode and the shared `tests/coverage` test directory.

bump some deps
* drop `num_cpus` from rust-installer as not used
* update `rayon`, `rayon-core`, which drops it's deps on `num_cpus` and `crossbeam-channel` (for bootstrap too) (https://github.com/rayon-rs/rayon/blob/v1.8.0/RELEASES.md)
* update `errno`, which drops `errno-dragonfly` (https://github.com/lambda-fairy/rust-errno/blob/5341791935df601306ffc57a665763c4ecd72755/CHANGELOG.md)

coverage: Unify `tests/coverage-map` and `tests/run-coverage` into `tests/coverage`
Ever since the introduction of the `coverage-map` suite, it's been awkward to have to manage two separate coverage test directories containing dozens of mostly-identical files.
However, those two suites were separate for good reasons. They have very different requirements (since only one of them requires actually running the test program), running only one suite is noticeably faster than running both, and having separate suites allows them to be blessed separately if desired. So while unifying them was an obvious idea, actually doing so was non-trivial.
---
Nevertheless, this PR finds a way to merge the two suites into one directory while retaining almost all of the developer-experience benefits of having two suites. This required non-trivial implementations of `Step`, but the end result works very smoothly.
---
The first 5 commits are a copy of #117340, which has been closed in favour of this PR.

drop num_cpus from rust-installer as not used
update rayon, rayon-core, which drops it's deps on num_cpus and crossbeam-channel (for bootstrap too) (https://github.com/rayon-rs/rayon/blob/v1.8.0/RELEASES.md)
update erro, which drops errno-dragonfly (https://github.com/lambda-fairy/rust-errno/blob/5341791935df601306ffc57a665763c4ecd72755/CHANGELOG.md)

Close #73497.
|
|
When multiple test modes share the same test directory, this will allow them to
avoid interfering with each others' files and timestamps.
|
|
These multi-file tests were not copied over in #114843 because they weren't
working, but it turns out that they just need the correct crate-type.
|
|
This is a step towards being able to unify the two coverage test directories.
There are two tests that require adjustment:
- `overflow.rs` requires an explicit `-Coverflow-checks=yes`
- `sort_groups.rs` is sensitive to provably unused instantiations

enable parallel rustc front end in nightly builds
Refers to the [MCP](https://github.com/rust-lang/compiler-team/issues/681), this pr does:
1. Enable the parallel front end in nightly builds, and keep the default number of threads as 1. Then users can use the parallel rustc front end via -Z threads=n option.
2. Set it up to serial front end for beta/stable builds via bootstrap.
3. Switch over the alt builders from parallel rustc to serial, so we have artifacts without parallel to test against the artifacts with parallel.

Add the `Span` of the `move` keyword to the HIR.
This is required to implement a lint like the one described here: https://github.com/rust-lang/rust-clippy/issues/11721

Remove license exception of `byteyarn` as it is no longer used
|
|
Run tidy license checker on more workspaces
The license checker didn't run on several workspaces before this PR. The same applied to the "external package sources" check. There were also two missing lockfiles which I have added now.
|
|
They've been deprecated for four years.
This commit includes the following changes.
- It eliminates the `rustc_plugin_impl` crate.
- It changes the language used for lints in
`compiler/rustc_driver_impl/src/lib.rs` and
`compiler/rustc_lint/src/context.rs`. External lints are now called
"loaded" lints, rather than "plugins" to avoid confusion with the old
plugins. This only has a tiny effect on the output of `-W help`.
- E0457 and E0498 are no longer used.
- E0463 is narrowed, now only relating to unfound crates, not plugins.
- The `plugin` feature was moved from "active" to "removed".
- It removes the entire plugins chapter from the unstable book.
- It removes quite a few tests, mostly all of those in
`tests/ui-fulldeps/plugin/`.
Closes #29597.

Most notably, this commit changes the `pub use crate::*;` in that file
to `use crate::*;`. This requires a lot of `use` items in other crates
to be adjusted, because everything defined within `rustc_span::*` was
also available via `rustc_span::source_map::*`, which is bizarre.
The commit also removes `SourceMap::span_to_relative_line_string`, which
is unused.

Clean up unchecked_math, separate out unchecked_shifts
Tracking issue: #85122
Changes:
1. Remove `const_inherent_unchecked_arith` flag and make const-stability flags the same as the method feature flags. Given the number of other unsafe const fns already stabilised, it makes sense to just stabilise these in const context when they're stabilised.
2. Move `unchecked_shl` and `unchecked_shr` into a separate `unchecked_shifts` flag, since the semantics for them are unclear and they'll likely be stabilised separately as a result.
3. Add an `unchecked_neg` method exclusively to signed integers, under the `unchecked_neg` flag. This is because it's a new API and probably needs some time to marinate before it's stabilised, and while it *would* make sense to have a similar version for unsigned integers since `checked_neg` also exists for those there is absolutely no case where that would be a good idea, IMQHO.
The longer-term goal here is to prepare the `unchecked_math` methods for an FCP and stabilisation since they've existed for a while, their semantics are clear, and people seem in favour of stabilising them.
