Fixes#98871
Show notice about "never used" of Debug for enum
Close#123068
If an ADT implements `Debug` trait and it is not used, the compiler says a note that indicates intentionally ignored during dead code analysis as [this note](2207179a59/tests/ui/lint/dead-code/unused-variant.stderr (L9)).
However this node is not shown for variants that have fields in enum. This PR fixes to show the note.
Suggest removing unused tuple fields if they are the last fields
Fixes#124556
We now check if dead/unused fields are the last fields of the tuple and suggest their removal instead of suggesting them to be changed to `()`.
Add pub struct with allow(dead_code) into worklist

Fixes#126289
This test was ignored long ago in
https://github.com/rust-lang/rust/pull/20578/ when the syntax for
closures was changed.
The current status is that a closure with an explicit `!` return type
will trigger the `unreachable_code` lint which appears to be the
original intent of the test
(https://github.com/rust-lang/rust/pull/16836). A closure without a
return type won't trigger the lint since the `!` type isn't inferred
(AFAIK). This restores the test to its original form.
