Don't derive Debug for `OnceWith` & `RepeatWith`

Closures don't impl Debug, so the derived impl is kinda useless. The behavior of not debug-printing closures is consistent with the rest of the iterator adapters/sources.
…ks, r=davidtwco

Add checks for the signature of the `start` lang item

Closes rust-lang#105963
Mention "signature" rather than "fn pointer" when impl/trait methods are incompatible

Fixes rust-lang#80929
Fixes rust-lang#67296
…r=Nilstrieb

Structured suggestion for `&mut dyn Iterator` when possible

Fix rust-lang#37914.
Document that `Vec::from_raw_parts[_in]` must be given a pointer from the correct allocator.

Currently, the documentation of `Vec::from_raw_parts` and `Vec::from_raw_parts_in` says nothing about what allocator the pointer must come from. This PR adds that missing information explicitly.
…y-err, r=estebank

Suppress type errors that come from private fields

Fixes rust-lang#57320

There was some discussion here (rust-lang#57320 (comment)), but I honestly think the second error is worth suppressing regardless.

I would be open to feedback though -- perhaps we can suppress the `.len()` suggestion if there's type error (since we have access to [`Expectation`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir_typeck/enum.Expectation.html), we can determine that).

Do not emit structured suggestion for turbofish with wrong span

Fix rust-lang#79161.
