7140: Store trait associated items in fst r=matklad a=SomeoneToIgnore
Store imported traits' associated function/methods and constants into `ImportMap.fst` and pefrorm the imports search on them.
This is a first step towards trait autoimport during completion functionality, the way I see it, after this PR, only a few major things are left to be done:
* store all traits' assoc items into fst, not only the ones in scope, as we do now. Any code pointers on how to do this are welcome 😄
* adjust a few modules in completions crate (`dot.rs`, `qualified_path.rs` at least) to query the import map, reusing the `import_assets` logic heavily
==
With the current import and autoimport implementations, it looks like for a single query, we're either interested in either associated items lookup or in all other `fst` contents lookup, but never both simultaneously.
I would rather not split `fst` in two but add another `Query` parameter to separate those, but let me know if you have any ideas.

7131: Created an assist for inlining a function's body into its caller r=matklad a=Michael-F-Bryan
This introduces an `inline_function` assist which will convert code like this:
```rust
fn add(a: u32, b: u32) -> u32 { a + b }
fn main() {
let x = add<|>(1, 2);
}
```
Into something like this:
```rust
fn add(a: u32, b: u32) -> u32 { a + b }
fn main() {
let x = {
let a = 1;
let b = 2;
a + b
};
}
```
Fixes#6863.

7162: Introduce queries to avoid problems when performing completion for enums with many variants r=matklad a=danielframpton
This change introduces two new queries to compute:
1) attributes for all variants of an enum, and
2) attributes for all fields of a variant.
The purpose of this change is to avoid the current n^2 behavior when rendering completion for variants (which prevents completion for enums with large numbers of variants).

7160: Get `hir::Function` return type r=flodiebold a=arnaudgolfouse
Hello !
As said in #7158, I noticed that `hir::Function` has no direct way of getting the return type, so this PR adds this functionality.

7147: ssr: Allow replacing expressions with statements r=davidlattimore a=MarijnS95
Depends on #6587
Until that is merged, the diff is https://github.com/MarijnS95/rust-analyzer/compare/stmt..replace-expr-with-stmt
---
Now that statements can be matched and replaced (#6587) some usecases require expressions to be replaced with statements as well. This happens when something that can ambiguously be an expression or statement like `if` and loop blocks appear in the last position of a block, as trailing expression. In this case a replacement pattern of the form `if foo(){$a();}==>>$a();` will only substitute `if` blocks in the list of statements but not if they (implicitly) end up in the trailing expression, where they are not wrapped by an EXPR_STMT (but the pattern and template are, as parsing only succeeds for the `stmt ==>> stmt` case).
Instead of adding two rules that match an expression - and emit duplicate matching errors - allow the template for expressions to be a statement if it fails to parse as an expression.
---
Another gross change that does not seem to break any tests currently, but perhaps a safeguard should be added to only allow this kind of replacement in blocks by "pushing" the replacement template to the statement list and clearing the trailing expression?

This is done by adding a `ret_type` method to `hir::Function`.
I followed `assoc_fn_params` convention by creating a new `RetType` type,
that contains the actual return type accessible via a `ty` method.
