The8472 6c67e55270 specialize in-place collection further via TrustedRandomAccess ...

This allows the optimizer to turn certain iterator pipelines such as

```rust
let vec = vec![0usize; 100];
vec.into_iter().map(|e| e as isize).collect::<Vec<_>>()
```

into a noop.

The optimization only applies when iterator sources are  `T: Copy`
since `impl TrustedRandomAccess for IntoIter<T>`.
No such requirement applies to the output type (`Iterator::Item`).
