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.

79ef13592e Completed the implementation of *size handling. 
Added some more cases to the test, and implemented a new lint,
cast_possible_wrap, triggered when casting from an unsigned type to a
signed type of the same size.

Added some tests to cover those cases, and a test I previously forgot.

lint.
Updated the test case to reflect changes.

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.
