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.

Ok, I lied in the title. This basically *removes* the problematic part
but:
  1) it was ugly with big bodies;
  2) it was not indented properly;
  3) it wasn’t very smart (see #675).

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.

8a10440641 utils: add match_type() helper function 
which saves one level of matching when checking for type paths

a437936d49 all: put often used DefPaths into utils as consts 
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
location, while we need the "canonical" location for the type checks.

Plus, the test suite catches all these cases.

ad0bc66402 Added support for isize/usize in the CastPass lint pass. 
Extracted the match that determines an integer types's size in a
utility function and implemented support for usize/isize.
Added a needed feature to the crate root.
Added some tests to cover those cases, and a test I previously forgot.
Silenced two errors signaled by dogfood.sh in unicode.rs.

dbc9b7f46e Reworked the error messages for more heplfulness. 
Renamed the cast_possible_overflow lint to cast_possible_truncation,
and updated the error message, readme and crate root accordingly.
Added some more information to the message for the cast_precision_loss
lint.
Updated the test case to reflect changes.
