a4a4a1854e Fix type parameter defaults
They should not be applied in expression or pattern contexts, unless there are
other explicitly given type args.

Merge #4651
4651: Use first match branch in case of type mismatch, not last r=kjeremy a=flodiebold

The comment says this was intentional, but I do agree with #4304 that it makes
more sense the other way around (for if/else as well).

Fixes #4304.

3f42b2e837 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.

85d44cad45 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);
    }
}
```

fe7bf993aa 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.

They're `&[u8; N]`, not `&[u8]` (see #4374).
