Esteban Küber 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

note: required for `i32` to implement `Foo`

error[E0277]: `PhantomPinned` cannot be unpinned
--> $DIR/pin-needed-to-poll-2.rs:43:18
|
LL | Pin::new(&mut self.sleep).poll(cx)
| -------- ^^^^^^^^^^^^^^^ within `Sleep`, the trait `Unpin` is not implemented for `PhantomPinned`, which is required by `Sleep: Unpin`
| |
| required by a bound introduced by this call
|
= note: consider using the `pin!` macro
consider using `Box::pin` if you need to access the pinned value outside of the current scope
note: required because it appears within the type `Sleep`
--> $DIR/pin-needed-to-poll-2.rs:8:8
|
LL | struct Sleep(std::marker::PhantomPinned);
| ^^^^^
note: required by a bound in `Pin::<Ptr>::new`
