Consider `Result<T, Uninhabited>` and `ControlFlow<Uninhabited, T>` to be equivalent to `T` for must use lint





This is an extension to rust-lang/rust#147382.

With this PR `Result<T, Uninhabited>` and `ControlFlow<Uninhabited, T>` considered as must use iif `T` must be used.

For such cases the lint will mention that `T` is wrapped in a `Result`/`ControlFlow` with an uninhabited error/break.

The reasoning here is that `Result<T, Uninhabited>` is equivalent to `T` in which values can be represented and thus the must-used-ness should also be equivalent.

Fixes rust-lang/rust#65861
