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.

cab9905705 better help text for "match -> if let" lint 
Implements the suggestion from #87.

Changes span_help_and_lint(), which is only used for this lint,
to use fileline_help() instead of span_help() to avoid printing
the span twice.

Also adds complete suggested new code. I had to distinguish
between blocks, which need no additionals braces, and other exprs.
