When a local binding shadows a function that is then called, this local
binding will cause an E0618 error. We now point not only at the binding
definition, but also at the locally defined function of the same name.
```
error[E0618]: expected function, found `&str`
--> $DIR/issue-22468.rs:3:13
|
LL | let foo = "bar";
| --- `foo` has type `&str`
LL | let x = foo("baz");
| ^^^-------
| |
| call expression requires function
...
LL | fn foo(file: &str) -> bool {
| -------------------------- this function of the same name is avalable here, but it shadowed by the local binding of the same name
```
