Update browser-ui-test version to 0.9.0
It adds the command `screenshot` and disables the screenshot comparison by default.

Make it possible to write doctests for bootstrap
This probably isn't super useful in practice, but it was easy to fix
and avoids confusing errors about mismatched versions between beta and the default toolchain.

[compiletest] Extract code to detect files related to a test into a different function
In the code that checks whether a test needs to be re-executed, compiletest checks the modification date of all the files related to the test. I need the list of files related to the test for other purposes inside compiletest, and while I could copy/paste the code `is_up_to_date` runs, that would produce incomplete results if more related files are added in the future.
This PR extracts the code to detect related files into a separate function, allowing the rest of compiletest to access the same data.

rustdoc: Resolve doc links referring to `macro_rules` items
cc https://github.com/rust-lang/rust/issues/81633
UPD: the fallback to considering *all* `macro_rules` in the crate for unresolved names is not removed in this PR, it will be removed separately and will be run through crater.

Move Derefer before Retag
_Follow up work to #96116 #95857 #95649_
This moves `Derefer` before `Retag` and creates a new `LocalInfo` called `Temp` to avoid retagging created temp values.

Add `do yeet` expressions to allow experimentation in nightly
Two main goals for this:
- Ensure that trait restructuring in https://github.com/rust-lang/rust/issues/84277#issuecomment-1066120333 doesn't accidentally close us off from the possibility of doing this in future, as sketched in https://rust-lang.github.io/rfcs/3058-try-trait-v2.html#possibilities-for-yeet
- Experiment with the *existence* of syntax for this, to be able to weight the syntax-vs-library tradeoffs better than we can right now. Notably the syntax (with `do`) and name in this PR are not intended as candidates for stabilization, but they make a good v0 PR for adding this with minimal impact to compiler maintenance or priming one possible name choice over another.

Also report the call site of PME errors locally.
Note this does not produce a full stack all the way to the first call that specifies all monomorphic parameters, it's just shallowly mentioning the last call site.

Make [e]println macros eagerly drop temporaries (for backport)
This PR extracts the subset of #96455 which is only the parts necessary for fixing the 1.61-beta regressions in #96434.
My larger PR #96455 contains a few other changes relative to the pre-#94868 behavior; those are not necessary to backport into 1.61.

Using an obviously-placeholder syntax. An RFC would still be needed before this could have any chance at stabilization, and it might be removed at any point.
But I'd really like to have it in nightly at least to ensure it works well with try_trait_v2, especially as we refactor the traits.

Erase type params when suggesting fully qualified path
When suggesting the use of a fully qualified path for a method call that
is ambiguous because it has multiple candidates, erase type params in
the resulting code, as they would result in an error when applied. We
replace them with `_` in the output to rely on inference. There might be
cases where this still produces slighlty incomplete suggestions, but it
otherwise produces many more errors in relatively common cases.

Fix duplicate directory separator in --remap-path-prefix.
The compiler will currently emit duplicate directory separators when `--remap-path-prefix` has an exact match of the working directory and it is invoked with a relative path to the main source file. For example
```bash
rustc src/main.rs -Cdebuginfo=2 --remap-path-prefix="$(pwd)=abc"
```
will produce the path `abc//src/main.rs` in debuginfo. This is because `some_path.join("")` will append a directory separator to `some_path` and then LLVM does not check if the working directory already ends a directory separator before concatenating it with the relative path.

Remove unnecessary environment variable in cf-protection documentation
Before merging the `cf-protection` flag, it was necessary to use a
locally-compiled version of `rustc`. This is no longer the case and the
documentation should reflect this.

Enforce Copy bounds for repeat elements while considering lifetimes
fixes https://github.com/rust-lang/rust/issues/95477
this is a breaking change in order to fix a soundness bug.
Before this PR we only checked whether the repeat element type had an `impl Copy`, but not whether that impl also had the appropriate lifetimes. E.g. if the impl was for `YourType<'static>` and not a general `'a`, then copying any type other than a `'static` one should have been rejected, but wasn't.

macros: subdiagnostic derive
Add a new macro, `#[derive(SessionSubdiagnostic)]`, which can be applied to structs that represent subdiagnostics, such as labels, notes, helps or suggestions.
`#[derive(SessionSubdiagnostic)]` can be used with the existing `#[derive(SessionDiagnostic)]`. All diagnostics implemented using either derive are translatable, and this new derive should make it easier to port existing diagnostics to using these derives.
For example, consider the following subdiagnostic types...
```rust
#[derive(SessionSubdiagnostic)]
pub enum ExpectedIdentifierLabel<'tcx> {
#[label(slug = "parser-expected-identifier")]
WithoutFound {
#[primary_span]
span: Span,
}
#[label(slug = "parser-expected-identifier-found")]
WithFound {
#[primary_span]
span: Span,
found: String,
}
}
#[derive(SessionSubdiagnostic)]
#[suggestion_verbose(slug = "parser-raw-identifier")]
pub struct RawIdentifierSuggestion<'tcx> {
#[primary_span]
span: Span,
#[applicability]
applicability: Applicability,
ident: Ident,
}
```
...and the corresponding Fluent messages:
```fluent
parser-expected-identifier = expected identifier
parser-expected-identifier-found = expected identifier, found {$found}
parser-raw-identifier = escape `{$ident}` to use it as an identifier
```
These can be emitted using the new `subdiagnostic` function on `Diagnostic`...
```rust
diag.subdiagnostic(ExpectedIdentifierLabel::WithoutFound { span });
diag.subdiagnostic(RawIdentifierSuggestion { span, applicability, ident });
```
...or as part of a larger `#[derive(SessionDiagnostic)]`:
```rust
#[derive(SessionDiagnostic)]
#[error(slug = "parser-expected-identifier")]
pub struct ExpectedIdentifier {
#[primary_span]
span: Span,
token_descr: String,
#[subdiagnostic]
label: ExpectedIdentifierLabel,
#[subdiagnostic]
raw_identifier_suggestion: Option<RawIdentifierSuggestion>,
}
```
```rust
sess.emit_err(ExpectedIdentifier { ... });
```

Revert diagnostic duplication and accidental stabilization
fixes #96460
this is an accidental stabilization that we should put into the beta. I believe it is low-risk, because it was literally what we had before #94081
The effect on tests is massive, but mostly deduplication of diagnostics and some minor span changes.
