87ef5f4d3b Lint against indexing and slicing
This can be useful to prevent panics in a codebase. ATM it is a pedantic
lint, but in the future it should be added to the restricions group.

5fadfb3ea6 Fix wrong suggestion in WHILE_LET_LOOP
Ok, I lied in the title. This basically *removes* the problematic part

  1) it was ugly with big bodies;
  2) it was not indented properly;
  3) it wasn’t very smart (see #675).

7e85db645e Fix another false positive in lifetime elision lint
The false positive occurred when we have an anonymous input lifetime and a
named output lifetime. This is not elidable, because if we elided the output
lifetime, it would be inferred to be the same as the input.

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.
