4412: infer: Make expected rhs type for plain assign the lhs type r=flodiebold a=kiljacken
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; // Was Option<{unknown}>, is now Option<bool>
loop {
end = Some(true);
}
}
```

4175: Introduce HirDisplay method for rendering source code & use it in add_function assist r=flodiebold a=TimoFreiberg
Next feature for #3639.
So far the only change in the new `HirDisplay` method is that paths are qualified, but more changes will be necessary (omitting the function name from function types, returning an error instead of printing `"{unknown}"`, probably more).
Is that approach okay?

This starts the transition to a new method of documenting the cfgs that are
enabled for a given crate in the json file. This is changing from a list
of atoms and a dict of key:value pairs, to a list of strings that is
equivalent to that returned by `rustc --print cfg ..`, and parsed in the
same manner by rust-analyzer.
This is the first of two changes, which adds the new field that contains
the list of strings. Next change will complete the transition and remove
the previous fields.
