fix: Copy lockfiles into target directory before invoking `cargo metadata`

|
feat: In "Fill match arms", allow users to prefer `Self` to the enum name when possible
|
|
feat: Add the quickfix for increasing visibility of a private field to the private-field diagnostic (previously it was only on no-such-field)

These error messages include lines of the standard library which have
changed and so need updated.

It isn't clear why the `Deref` impl isn't found for this in a stage two
build, but presumably relates to `rustc_middle::ty::RawList` containing
an extern type and `Deref` not yet being relaxed to `PointeeSized` (this
is technically a breaking change but unlikely to be one and will be
tested in a follow-up).
|
|
One clippy test is `no_core` and needs to have `MetaSized` and
`PointeeSized` added to it.
|
|
Existing lints that had special-casing for `Sized` predicates ought
to have these same special cases applied to `MetaSized` predicates.

Reduce precedence of expressions that have an outer attr
Previously, `-Zunpretty=expanded` would expand this program as follows:
```rust
#![feature(stmt_expr_attributes)]
macro_rules! repro {
($e:expr) => {
#[allow(deprecated)] $e
};
}
#[derive(Default)]
struct Thing {
#[deprecated]
field: i32,
}
fn main() {
let thing = Thing::default();
let _ = repro!(thing).field;
}
```
```rs
#![feature(prelude_import)]
#![feature(stmt_expr_attributes)]
#[prelude_import]
use std::prelude::rust_2021::*;
#[macro_use]
extern crate std;
struct Thing {
#[deprecated]
field: i32,
}
#[automatically_derived]
impl ::core::default::Default for Thing {
#[inline]
fn default() -> Thing {
Thing { field: ::core::default::Default::default() }
}
}
fn main() {
let thing = Thing::default();
let _ = #[allow(deprecated)] thing.field;
}
```
This is not the correct expansion. The correct output would have `(#[allow(deprecated)] thing).field` with the attribute applying only to `thing`, not to `thing.field`.

Unimplement unsized_locals
Implements https://github.com/rust-lang/compiler-team/issues/630
Tracking issue here: https://github.com/rust-lang/rust/issues/111942
Note that this just removes the feature, not the implementation, and does not touch `unsized_fn_params`. This is because it is required to support `Box<dyn FnOnce()>: FnOnce()`.
There may be more that should be removed (possibly in follow up prs)
- the `forget_unsized` function and `forget` intrinsic.
- the `unsized_locals` test directory; I've just fixed up the tests for now
- various codegen support for unsized values and allocas

``@rustbot`` label F-unsized_locals
Fixes rust-lang/rust#79409

Temporary lifetime extension through tuple struct and tuple variant constructors
This makes temporary lifetime extension work for tuple struct and tuple variant constructors, such as `Some()`.
Before:
```rust
let a = &temp(); // Extended
let a = Some(&temp()); // Not extended :(
let a = Some { 0: &temp() }; // Extended
```
After:
```rust
let a = &temp(); // Extended
let a = Some(&temp()); // Extended
let a = Some { 0: &temp() }; // Extended
```
So, with this change, this works:
```rust
let a = Some(&String::from("hello")); // New: String lifetime now extended!
println!("{a:?}");
```
Until now, we did not extend through tuple struct/variant constructors (like `Some`), because they are function calls syntactically, and we do not want to extend the String lifetime in:
```rust
let a = some_function(&String::from("hello")); // String not extended!
```
However, it turns out to be very easy to distinguish between regular functions and constructors at the point where we do lifetime extension.
In practice, constructors nearly always use UpperCamelCase while regular functions use lower_snake_case, so it should still be easy to for a human programmer at the call site to see whether something qualifies for lifetime extension or not.
This needs a lang fcp.
---
More examples of what will work after this change:
```rust
let x = Person {
name: "Ferris",
job: Some(&Job { // `Job` now extended!
title: "Chief Rustacean",
organisation: "Acme Ltd.",
}),
};
dbg!(x);
```
```rust
let file = if use_stdout {
None
} else {
Some(&File::create("asdf")?) // `File` now extended!
};
set_logger(file);
```
```rust
use std::path::Component;
let c = Component::Normal(&OsString::from(format!("test-{num}"))); // OsString now extended!
assert_eq!(path.components.first().unwrap(), c);
```
