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.

7620: Support control flow in `extract_function` assist r=matklad a=cpud36

Support `return`ing from outer function, `break`ing and `continue`ing outer loops when extracting function.

# Example
Transforms
```rust
fn foo() -> i32 {
  let items = [1,2,3];
  let mut sum = 0;
  for &item in items {
    <|>if item == 42 {
      break;
    }<|>
    sum += item;
  }
  sum
}
```
Into 
```rust
fn foo() -> i32 {
  let items = [1,2,3];
  let mut sum = 0;
  for &item in items {
    if fun_name(item) {
      break;
    }
    sum += item;
  }
  sum
}

fn fun_name(item: i32) -> bool {
  if item == 42 {
    return true;
  }
  false
}
```

# Features

Supported variants
- break and function does not return => uses `bool` and plain if
- break and function does return => uses `Option<T>` and matches on it
- break with value and function does not return => uses `Option<T>` and if let
- break with value and function does return => uses `Result<T, U>` and matches on t
- same for `return` and `continue`(but we can't continue with value)

Assist does handle nested loops and nested items(like functions, modules, impls)

Try `expr?` operator is allowed together with `return Err(_)` and `return None`.
`return expr` is not allowed.

# Not supported
## Mixing `return` with `break` or `continue`
If we have e.g. a `return` and a `break` in the selected code, it is unclear what the produced code should look like.
We can try `Result<T, Option<U>>` or something like that, but it isn't idiomatic, nor it is established. Otherwise, implementation
is relatively simple.

## `break` with label
Not sure how to handle different labels for multiple `break`s.

[edit] implemented try `expr?`

7535: Extract function assist r=cpud36 a=cpud36

This PR adds `extract function/method` assist. closes #5409.

# Supported features
Assist should support extracting from expressions(`1`, `2 + 2`, `loop { }`) and from a series of statements, e.g.:
```rust
foo();
$0bar();
baz();$0
quix();
```
Assist also supports extracting parameters, like:
```rust
fn foo() -> i32 {
  let n = 1;
  $0n + 1$0
}

// -
fn foo() -> i32 {
  let n = 1;
  fun_name(n)
}

fn fun_name(n: i32) -> i32 {
  n + 1
}
```

Extracting methods also generally works.

Assist allows referencing outer variables, both mutably and immutably, and handles handles access to variables local to extracted function:
```rust
fn foo() {
  let mut n = 1;
  let mut m = 2;
  let mut moved_v = Vec::new();
  let mut ref_mut_v = Vec::new();
  $0
  n += 1;
  let k = 1;
  moved_v.push(n);
  let r = &mut m;
  ref_mut_v.push(*r);
  let h = 3;
  $0
  n = ref_mut_v.len() + k;
  n -= h + m;
}

// -
fn foo() {
  let mut n = 1;
  let mut m = 2;
  let mut moved_v = Vec::new();
  let mut ref_mut_v = Vec::new();
 
  let (k, h) =  fun_name(&mut n, moved_v, &mut m, &mut ref_mut_v);

  n = ref_mut_v.len() + k;
  n -= h + m;
}

fn fun_name(n: &mut i32, mut moved_v: Vec<i32>, m: &mut i32, ref_mut_v: &mut Vec<i32>) -> (i32, i32) {
  *n += 1;
  let k = 1;
  moved_v.push(*n);
  let r = m;
  ref_mut_v.push(*r);
  let h = 3;
  (k, h)
}
```

So we handle both input and output paramters

# Working with non-`Copy` types

Consider the following example:
```rust
fn foo() {
  let v = Vec::new();
  $0
  let n = v.len();
  $0
  let is_empty = v.is_empty();
}
```
`v` must be a parameter to extracted function. 
The question is, what type should it have.
It could be `v: Vec<i32>`, or `v: &Vec<i32>`. 
The former is incorrect for `Vec<i32>`, but the later is silly for `i32`.

To resolve this we need to know if the type implements `Copy` trait.

I didn't find any api available from assists to query this. 
`hir_ty::method_resolution::implements` seems relevant, but is isn't publicly re-exported from `hir`.

# Star(`*`) token and pointer dereference

If I understand correctly, in order to create expression like `*p`, one should use `ast::make::expr_prefix(T![*], ...)`, which
in turn calls `token(T![*])`.

`token` does not have star in `tokens::SOURCE_FILE`, so this panics.
I had to add `*` to `SOURCE_FILE` to make it work.

Correct me if this is not intended way to do this.

# Lowering access `value -> mut ref -> shared ref`

Consider the following example:
```rust
fn foo() {
  let v = Vec::new();
  $0 let n = v.len(); $0
}
```
`v` is not used after extracted function body, so both `v: &Vec<i32>` and `v: Vec<i32>` would work.
Currently the later would be chosen.

We can however check the body of extracted function and conclude that `v: &Vec<i32>` is sufficient.
Using `v: &Vec<i32>`(that is a minimal required access level) might be a better default.
I am unsure.

# Cleanup
The assist seems to be reasonably handling most of common cases.
If there are no concerns with code it produces(i.e. with test cases), I will start cleaning up

[edit]
added showcase

6587: SSR: Support statement matching and replacing r=davidlattimore a=MarijnS95


For #3186

Hi!

This is a smaller initial patchset that came up while working on support for statement lists (and my first time working on RA 😁). It has me stuck on trailing semicolons for which I hope to receive some feedback. Matching (and replacing) `let` bindings with a trailing semicolon works fine, but trying to omit these (to make patterns more ergonomic) turns out more complex than expected.

The "optional trailing semicolon solution" implemented in this PR is ugly because `Matcher::attempt_match_token` should only consume a trailing `;` when parsing `let` bindings to prevent other code from breaking. That at the same time has a nasty side-effect of `;` ending up in the matched code: any replacements on that should include the trailing semicolon as well even if it was not in the pattern. A better example is in the tests:

3ae1649c24/crates/ssr/src/tests.rs (L178-L184)

The end result to achieve is (I guess) allowing replacement of let bindings without trailing semicolon like `let x = $a ==>> let x = 1` (but including them on both sides is still fine), and should make replacement in a macro call (where `foo!(let a = 2;)` for a `$x:stmt` is invalid syntax) possible as well. That should allow to enable/fix these tests:

3ae1649c24/crates/ssr/src/tests.rs (L201-L214)

A possible MVP of this PR might be to drop this optional `;' handling entirely and only allow an SSR pattern/template with semicolons on either side.

6331: correct hover text for items with doc attribute with raw strings r=matklad a=JoshMcguigan

Fixes #6300 by improving the handling of raw string literals in attribute style doc comments.

This still has a bug where it could consume too many `"` at the start or end of the comment text, just as the original code had. Not sure if we want to fix that as part of this PR or not? If so, I think I'd prefer to add a unit test for either the `as_simple_key_value` function (I'm not exactly sure where this would belong / how to set this up) or create a `fn(&SmolStr) -> &SmolStr` to unit test by factoring out the `trim` operations from `as_simple_key_value`. Thoughts on this? 

6342: Shorter dependency chain r=matklad a=popzxc

Continuing implementing suggestions from the `Completion refactoring` zulip thread.

This PR does the following:

- Removes dependency of `completions` on `assists` by moving required functionality into `ide_db`.
- Moves completely `call_info` crate into `ide_db` as it looks like it fits perfect there.
- Adds a bunch of new tests and docs.
- Adds the re-export of `base_db` to the `ide_db` and removes direct dependency on `base_db` from other crates.

The last point is controversial, I guess, but I noticed that in places where `ide_db` is used, `base_db` is also *always* used. Thus I think the dependency on the `base_db` is implied by the fact of `ide_db` interfaces, and thus it makes sense to just provide `base_db` out of the box.

6172: Add qualify path assist r=matklad a=Veykril

This implements a `qualify_path` assist which works quite similar to the `auto_import` assist but instead of adding imports to the file it well, qualifies the path. This PR also moves out the `AutoImportAssets` struct and functions from `auto_import` into a utils submodule as most of this is now shared between `auto_import` and `qualify_path`.

Changes made to `AutoImportAssets` are solely in its `search_for_imports` function which now takes a prefixed parameter to discern between using `find_use_path_prefixed` and `find_use_path` as the former is the required behavior by `auto_import` and the latter by this assist.

For missing imported traits instead of importing this will qualify the path with a trait cast as in:
```rust
test_mod::TestStruct::TEST_CONST<|>
```
becomes
```rust
<test_mod::TestStruct as test_mod::TestTrait>::TEST_CONST
```

and for trait methods ideally it would do the following:
```rust
let test_struct = test_mod::TestStruct {};
test_struct.test_meth<|>od()
```
becomes
```rust
let test_struct = test_mod::TestStruct {};
test_mod::TestTrait::test_method(&test_struct)
```

Fixes #4124.

6019: Remove make::path_from_text r=matklad a=Veykril

This removes the `make::path_from_text` function, which according to a note should've been private. I removed it since it didn't really serve a purpose as it was simply wrapping `make::ast_from_text`.
