Adds more details about how a significant drop in a match scrutinee can
cause a deadlock and include link to documentation. Emits messages
indicating temporaries with significant drops in arms of matches and
message about possible deadlocks/unexpected behavior.
changelog: Add more details to significant drop lint to explicitly show
how temporaries in match scrutinees can cause deadlocks/unexpected
behavior.
feat(fix): ignore `todo!` and `unimplemented!` in `if_same_then_else`
close: #8836
take over: #8853
This PR adds check `todo!` and `unimplemented!` in if_same_then_else.
( I thought `unimplemented` should not be checked as well as todo!.)
Thank you in advance.

Use `RefCell` in `needless_return` tests

The stdio locks no longer fail to compile if the `return` is removed due to them now being `'static` (#9008)

Make `ExprKind::Closure` a struct variant.
Simple refactor since we both need it to introduce additional fields in `ExprKind::Closure`.

Rework `branches_sharing_code`
fixes#7378
This changes the lint from checking pairs of blocks, to checking all the blocks at the same time. As such there's almost none of the original code left.
changelog: Don't lint `branches_sharing_code` when using different binding names
And likewise for the `Const::val` method.
Because its type is called `ConstKind`. Also `val` is a confusing name
because `ConstKind` is an enum with seven variants, one of which is
called `Value`. Also, this gives consistency with `TyS` and `PredicateS`
which have `kind` fields.
The commit also renames a few `Const` variables from `val` to `c`, to
avoid confusion with the `ConstKind::Value` variant.
Test metadata collection in Bors CI workflow
This PR adds a new check to bors CI workflows, which ensures that the metadata collection success, when it's run as part of the `deploy` script. I've only added it to bors workflows, as the runtime will be high while it'll also succeed most of the time. This is a preparation for rust-lang/rust-clippy#8947.

Fix some `#[expect]` lint interaction
Fixing the first few lints that aren't caught by `#[expect]`. The root cause of these examples was, that the lint was emitted at the wrong location.
