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.

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.

846c164709 don't say "did you mean to" - use the standard "consider..." 
"Did you mean to ..." sounds a bit condescending to me, since
if I meant to write "if let" I probably wouldn't have written "match" :)

Also remove the "use xxx;" blocks to ensure import paths don't change.
They don't work anyway since stuff may still be re-exported at the old

Plus, the test suite catches all these cases.

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.
