820e2680ec handle ascription type op in NLL HRTB diagnostics 
Refactors the `type_op_ascribe_user_type` query into a version which
accepts a span, and uses it in the nicer NLL HRTB bound region errors.

e8910440a2 select obligations after check_casts 
Otherwise, we can get into a situation where you have
a subtype obligation `#1 <: #2` pending, #1 is constrained
by `check_casts`, but #2` is unaffected.

Rollup merge of #88232 - m-ou-se:macro-name-imported-but-not-macro, r=estebank 
Add notes to macro-not-found diagnostics to point out how things with the same name were not a match.

This adds notes like:
```
error: cannot find derive macro `Serialize` in this scope
  --> $DIR/issue-88206.rs:22:10
   |
LL | #[derive(Serialize)]
   |          ^^^^^^^^^
   |
note: `Serialize` is imported here, but it is not a derive macro
  --> $DIR/issue-88206.rs:17:11
   |

Rollup merge of #88230 - steffahn:a_an, r=oli-obk 
Fix typos “a”→“an”

Fix typos in comments; found using a regex to find some easy instance of incorrect usage of a vs. an.

While automation was used to find these, every change was checked manually.

_For `clippy`, I don’t know if the changes should better better be moved to a PR to the original repo._

<hr>

This has some overlap with #88226, but neither is a strict superset of the other.

If you want multiple commits, I can split it up; in that case, make sure to suggest a criterion for splitting.

9c44d80c83 add Cell::as_array_of_cells, similar to Cell::as_slice_of_cells 
Previously, converting `&mut [T; N]` to `&[Cell<T>; N]` looks like this:

    let array = &mut [1, 2, 3];
    let cells: &[Cell<i32>; 3] = Cell::from_mut(&mut array[..])
        .as_slice_of_cells()
        .try_into()
        .unwrap();

With this new helper method, it looks like this:

    let array = &mut [1, 2, 3];
    let cells: &[Cell<i32>; 3] = Cell::from_mut(array).as_array_of_cells();
