7956: Add assist to convert for_each into for loops r=Veykril a=SaiintBrisson

This PR resolves #7821.
Adds an assist to that converts an `Iterator::for_each` into a for loop: 

```rust
fn main() {
    let vec = vec![(1, 2), (2, 3), (3, 4)];
    x.iter().for_each(|(x, y)| {
        println!("x: {}, y: {}", x, y);
    })
}
```
becomes
```rust
fn main() {
    let vec = vec![(1, 2), (2, 3), (3, 4)];
    for (x, y) in x.iter() {
        println!("x: {}, y: {}", x, y);
    });
}
```

7873: Consider unresolved qualifiers during flyimport r=matklad a=SomeoneToIgnore

Closes https://github.com/rust-analyzer/rust-analyzer/issues/7679

Takes unresolved qualifiers into account, providing better completions (or none, if the path is resolved or do not match).

Does not handle cases when both path qualifier and some trait has to be imported: there are many extra issues with those (such as overlapping imports, for instance) that will require large diffs to address.

Also does not do a fuzzy search on qualifier, that requires some adjustments in `import_map` for better queries and changes to the default replace range which also seems relatively big to include here.

![qualifier_completion](https://user-images.githubusercontent.com/2690773/110040808-0af8dc00-7d4c-11eb-83db-65af94e843bb.gif)

7898: generate_function assist: infer return type r=JoshMcguigan a=JoshMcguigan

This PR makes two changes to the generate function assist:

1. Attempt to infer an appropriate return type for the generated function
2. If a return type is inferred, and that return type is not unit, don't render the snippet

```rust
fn main() {
    let x: u32 = foo$0();
    //              ^^^ trigger the assist to generate this function
}

// BEFORE
fn foo() ${0:-> ()} {
    todo!()
}

// AFTER (only change 1)
fn foo() ${0:-> u32} {
    todo!()
}

// AFTER (change  1 and 2, note the lack of snippet around the return type)
fn foo() -> u32 {
    todo!()
}
```

These changes are made as two commits, in case we want to omit change 2. I personally feel like it is a nice change, but I could understand there being some opposition.

#### Pros of change 2
If we are able to infer a return type, and especially if that return type is not the unit type, the return type is almost as likely to be correct as the argument names/types. I think this becomes even more true as people learn how this feature works.

#### Cons of change 2

We could never be as confident about the return type as we are about the function argument types, so it is more likely a user will want to change that. Plus it is a confusing UX to sometimes have the cursor highlight the return type after triggering this assist and sometimes not have that happen.

#### Why omit unit type?

The assumption is that if we infer the return type as unit, it is likely just because of the current structure of the code rather than that actually being the desired return type. However, this is obviously just a heuristic and will sometimes be wrong. But being wrong here just means falling back to the exact behavior that existed before this PR.

7741: Add convert_for_to_iter_for_each assist r=mattyhall a=mattyhall

Implements one direction of #7681 

I wonder if this tries to guess too much at the right thing here. A common pattern is:

```rust
let col = vec![1, 2, 3];
for v in &mut col {
  *v *= 2;
}
// equivalent to:
col.iter_mut().for_each(|v| *v *= 2);
```

I've tried to detect this case by checking if the expression after the `in` is a (mutable) reference and if not inserting iter()/iter_mut(). This is just a convention used in the stdlib however, so could sometimes be wrong. I'd be happy to make an improvement for this, but not sure what would be best. A few options spring to mind:
1. Only allow this for types that are known to have iter/iter_mut (ie stdlib types)
2. Try to check if iter/iter_mut exists and they return the right iterator type
3. Don't try to do this and just add `.into_iter()` to whatever is after `in`
