Oliver Schneider 902c7d832b fix cc computation in the presence of diverging calls 
CFG treats diverging calls as its completely own path out of the function.
While this makes sense, it should also mean that a panic should increase the cyclomatic
complexity. Instead it decreases it.

Minimal example:

```rust
if a {
    b
} else {
    panic!("cake");
}
d
```

creates the following graph

```dot
digraph G {
  "if a" -> "b"
  "if a" -> "panic!(\"cake\")"
  "b" -> c
}
```

which has a CC of 1 (3 - 4 + 2). A CC of 1 means there is one path through the program.
Obviously that is wrong. There are two paths. One returning normally, and one panicking.

Cesar Eduardo Barros 8e59be318c Mention VecDeque in linkedlist lint 
I couldn't find anything named RingBuf in the standard library. Some
search revealed that it had been renamed to VecDeque before the first
stable Rust release.
