bors 0fb00251a5 Auto merge of #78662 - sexxi-goose:add_expr_id_to_delegate, r=nikomatsakis 
Provide diagnostic suggestion in ExprUseVisitor Delegate

The [Delegate trait](981346fc07/compiler/rustc_typeck/src/expr_use_visitor.rs (L28-L38)) currently use `PlaceWithHirId` which is composed of Hir `Place` and the
corresponding expression id.

Even though this is an accurate way of expressing how a Place is used,
it can cause confusion during diagnostics.

Eg:

```
let arr : [String; 5];

let [a, ...]     =   arr;
 ^^^ E1 ^^^      =  ^^E2^^
 ```

 Here `arr` is moved because of the binding created E1. However, when we
 point to E1 in diagnostics with the message `arr` was moved, it can be
 confusing.  Rather we would like to report E2 to the user.

 Closes: https://github.com/rust-lang/project-rfc-2229/issues/20
