### What it does
Checks for `Into`, `TryInto`, `From`, `TryFrom`, or `IntoIter` calls
which uselessly convert to the same type.

### Why is this bad?
Redundant code.

### Example
```
// format!() returns a `String`
let s: String = format!("hello").into();
```

Use instead:
```
let s: String = format!("hello");
```
