Move some tests to more reasonable directories - 2
All tests with a score equal or greater than 1.0 were moved to their respective directories by issuing
```bash
cat FILE | tr -s " " | tr -d '():' | sort -k3 | awk '$3 >= 1' | cut -d " " -f1-2 | sed 's;\\;/;g' | xargs -n2 git mv
```
**Observation**: The first column values is the only column with results greater zero
To attest the confidentiality of the model, some manual revision of at least of tests is needed and this process will be tracked in the following list:
* `src/test/ui/abi/issue-28676.rs` OK #28676
* `src/test/ui/array-slice-vec/issue-15730.rs` OK
* `src/test/ui/associated-types/issue-24338.rs` OK #54823
* `src/test/ui/associated-types/issue-48551.rs` Looks OK #48551
* `src/test/ui/associated-types/issue-50301.rs` Looks OK #63577

Rework diagnostics for wrong number of generic args (fixes#66228 and #71924)
This PR reworks the `wrong number of {} arguments` message, so that it provides more details and contextual hints.
This makes it possible to pass the `Impl` directly to functions, instead
of having to pass each of the many fields one at a time. It also
simplifies matches in many cases.
Enable ASan, TSan, UBSan for aarch64-apple-darwin.
I confirmed ASan, TSan, UBSan all work for me locally with `clang` on my new Macbook Air.

In which we start to parse const generics defaults
As discussed in this [zulip topic](https://rust-lang.zulipchat.com/#narrow/stream/260443-project-const-generics/topic/const.20generic.20defaults), this PR extracts the parsing parts from `@JulianKnodt's` PR #75384 for a better user-experience using the newly stabilized `min_const_generics` (albeit temporary) as shown in #80507: trying to use default values on const generics currently results in parse errors, as if the user didn't use the correct syntax (which is somewhat true but also misleading).
This PR extracts (and slightly modifies in a couple places) `@JulianKnodt's` parsing code (with attribution if I've done everything correctly), AST and HIR changes, and feature gate setup.
This feature is now marked as "incomplete" and thus will also print out the expected "const generics default values are unstable" error instead of a syntax error. Note that, as I've only extracted the parsing part, the actual feature will not work at all if enabled. There will be ICEs, and inference errors on the const generics default values themselves.
Fixes#80507.
Once this merges, I'll:
- modify the const generics tracking issue to refer to the `const_generics_defaults` gate rather than the older temporary name it uses there.
- create the GH `F-const_generics_defaults` label
r? `@varkor`
- Adds optional default values to const generic parameters in the AST
and HIR
- Parses these optional default values
- Adds a `const_generics_defaults` feature gate
Only produce .xz tarballs on CI
This PR adds a `./configure` option to choose which tarball compression formats to produce, and changes our CI configuration to only produce `.xz` tarballs. The release process will then recompress everything into `.gz` when producing a release.
This will drastically reduce our storage costs for CI artifacts, as we'd stop storing the same data twice. **Stable, beta and nightly releases will not be affected by this at all.**
Before landing this we'll need to increase the VM size of our release process, to recompress everything in a reasonable amount of time.

Lint on redundant trailing semicolon after item
We now lint on code like this:
```rust
fn main() {
fn foo() {};
struct Bar {};
}
```
Previously, this caused warnings in Cargo, so it was disabled.
https://github.com/alexcrichton/curl-rust/pull/351 changed
curl-rust to no longer enable the default features of libz-sys.
Because rustfmt includes rustc-workspace-hack with the
rustc-workspace-hack/all-static feature (sometimes), it ends up building
libz-sys without the default features. This causes a duplicate
with other packages (like rls) which enable the default
features.
Clippy: Revert change from last sync
r? `@Manishearth`
cc `@ebroto`
Note that the commit e898015 doesn't exist like this in the Clippy repo. I didn't want to do a full sync, because this would've included at least one new lint, which I wanted to avoid a week before beta is branched. This just reverts one commit from the last sync.
Utilize PGO for rustc linux dist builds
This implements support for applying PGO to the rustc compilation step (not
standard library or any tooling, including rustdoc). Expanding PGO to more tools
is not terribly difficult but will involve more work and greater CI time
commitment.
For the same reason of avoiding greater implementation time commitment,
implementing for platforms outside of x86_64-unknown-linux-gnu is skipped.
In practice it should be quite simple to extend over time to more platforms. The
initial implementation is intentionally minimal here to avoid too much work
investment before we start seeing wins for a subset of Rust users.
The choice of workloads to profile here is somewhat arbitrary, but the general
rationale was to aim for a small set that largely avoided time regressions on
perf.rust-lang.org's full suite of crates. The set chosen is libcore, cargo (and
its dependencies), and a few ad-hoc stress tests from perf.rlo. The stress tests
are arguably the most controversial, but they benefit those cases (avoiding
regressions) and do not really remove wins from other benchmarks.
The primary next step after this PR lands is to implement support for PGO in
LLVM. It is unclear whether we can afford a full LLVM rebuild in CI, though, so
the approach taken there may need to be more staggered. rustc-only PGO seems
well affordable on linux at least, giving us up to 20% wall time wins on some
crates for 15 minutes of extra CI time (1 hour with this PR, up from 45 minutes).
The PGO data is uploaded to allow others to reuse it if attempting to reproduce
the CI build or potentially, in the future, on other platforms where an
off-by-one strategy is used for dist builds at minimal performance cost.
