6efddac288 Provide more context on derived obligation error primary label
Expand the primary span of E0277 when the immediate unmet bound is not what the user wrote:

```
error[E0277]: the trait bound `i32: Bar` is not satisfied
 --> f100.rs:6:6
  |
6 |     <i32 as Foo>::foo();
  |      ^^^ the trait `Bar` is not implemented for `i32`, which is required by `i32: Foo`
  |
help: this trait has no implementations, consider adding one
 --> f100.rs:2:1
  |
2 | trait Bar {}
  | ^^^^^^^^^
note: required for `i32` to implement `Foo`
 --> f100.rs:3:14
  |
3 | impl<T: Bar> Foo for T {}
  |         ---  ^^^     ^
  |         |
  |         unsatisfied trait bound introduced here
```

Rollup merge of #120424 - RalfJung:raw-ptr-meta, r=Nilstrieb
raw pointer metadata API: data address -> data pointer

A pointer consists of [more than just an address](https://github.com/rust-lang/rfcs/pull/3559), so let's not equate "pointer" and "address" in these docs.

8bd8f3b090 Suggest unwrap() on field not found for Result/Option
When encountering a `Result<T, _>` or `Option<T>` where `T` has a field
that's being accessed, suggest calling `.unwrap()` to get to the field.
