Since a7c25b2 removed `in-band` from code
headers, the only remaining uses of the `in-band` class are:

Since all of these uses are nested below `h1.fqn`, we can get rid of it,
and the support code that was used for when `in-band` was part of item
rendering.

Closes rust-lang#102643

Suggest calling method if fn does not exist

I tried to split this up into two commits, the first where we stash the resolution error until typeck (which causes a bunch of diagnostics changes because the ordering of error messages change), then the second commit is the actual logic that actually implements the suggestion.

I am not in love with the presentation of the suggestion, so I could use some advice for how to format the actual messaging.

Fixes rust-lang#102518

Suggest `==` to wrong assign expr

Given the following code:

```rust
fn main() {
    let x = 3;
    let y = 3;
    if x == x && y = y {
        println!("{}", x);
    }
}
```

Current output is:

```
error[E0308]: mismatched types
 --> src/main.rs:4:18
  |
4 |     if x == x && y = y {
  |                  ^ expected `bool`, found integer

error[E0308]: mismatched types
 --> src/main.rs:4:8
  |
4 |     if x == x && y = y {
  |        ^^^^^^^^^^^^^^^ expected `bool`, found `()`
```

This adds a suggestion:

```diff
error[E0308]: mismatched types
 --> src/main.rs:6:18
  |
6 |     if x == x && y = y {
  |                  ^ expected `bool`, found integer

error[E0308]: mismatched types
 --> src/main.rs:6:8
  |
6 |     if x == x && y = y {
  |        ^^^^^^^^^^^^^^^ expected `bool`, found `()`
  |
+ help: you might have meant to compare for equality
+   |
+ 6 |     if x == x && y == y {
+   |                     +
```

And this fixes a part of rust-lang#97469

The current stderr looks slightly different from [source](https://github.com/rust-lang/rust/pull/83915/files#diff-8c64c576ccaceb816e71d2279a6ee4bf79211bc06f55c46dda3f98a18748ad7a), so I used the latest one from nightly. Do let me know if anything is wrong.
