Handle Self in values and patterns
...
I.e.
- `Self(x)` or `Self` in tuple/unit struct impls
- `Self::Variant(x)` or `Self::Variant` in enum impls
- the same in patterns
Fixes #4454 .

infer: Make expected rhs type for plain assign the lhs type
...
This fixes an issue where the following code sample would fail to infer
the type contained in the option:
```rust
fn main() {
let mut end = None; // TODO: Fix inference for this in RA
loop {
end = Some(true);
}
}
```

Implement better handling of divergence
...
Divergence here means that for some reason, the end of a block will not be
reached. We tried to model this just using the never type, but that doesn't work
fully (e.g. in `let x = { loop {}; "foo" };` x should still have type `&str`);
so this introduces a `diverges` flag that the type checker keeps track of, like
rustc does.
