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.

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.
