Rollup merge of #116841 - chenyukang:yukang-suggest-unwrap-expect, r=b-naber 
Suggest unwrap/expect for let binding type mismatch

Found it when investigating https://github.com/rust-lang/rust/issues/116738
I'm not sure whether it's a good style to suggest `unwrap`, seems it's may helpful for newcomers.

#116738 needs another fix to improve it.

Rollup merge of #116990 - estebank:issue-68445, r=cjgillot 
Mention `into_iter` on borrow errors suggestions when appropriate

If we encounter a borrow error on `vec![1, 2, 3].iter()`, suggest `into_iter`.

Fix #68445.
