11061: Support "move if to guard" for if else chains r=weirane a=weirane
The idea is to first parse the if else chain into a vector of `(Condition, BlockExpr)`s until we reach an iflet branch, an else branch, or the end (the tail). Then add the match arms with guard for the vector, and add the tail with no if guard.
Because the whole original match arm is replaced and the generated code doesn't have redundent commas, I removed redundent commas in some test cases.
Closes#11033.

11062: fix: Don't say "a reference to" for `Copy` types in the generate getter assist r=Veykril a=patrick-gu
This changes the generate getter assist to not say "a reference to" in the documentation stub if the type is `Copy`, as the getter does not return a reference.
To determine whether the type is `Copy`, I have added an `is_copy` method to `ReferenceConversion`.

11017: Support "move if to guard" with an else branch r=Veykril a=weirane
Support the assist `move_arm_cond_to_match_guard` when there is an else branch.
I have two questions:
1. How to indent the first line of a match arm? `matcharm.indent()` doesn't seem to work. so I hard coded four spaces here:
95a0de85d5/crates/ide_assists/src/handlers/move_guard.rs (L162-L163)
2. I find a little issue in the original implementation, this code
```rust
let y = match 92 {
x => {
if x == 0 {$0
false
}
}
_ => true,
};
```
will be transformed to
```rust
let y = match 92 {
x if x == 0 => false
_ => true,
};
```
a comma is missing after the `false`. Should I also fix that? Or this can go in a separate PR.
Closes#10997.

11000: fix: insert whitespaces into assoc items for assist when macro generated r=Veykril a=Veykril
This is obviously only a temporary hack which still produces ugly looking items, but as long as the syntax is valid one can at least have rustfmt fix the formatting again.

10986: fix: Fix lint completions not working for unclosed attributes r=Veykril a=Veykril
Fixes#10682
Uses keywords and nested `TokenTree`s as a heuristic to figure out when to stop parsing in case the attribute is unclosed which should work pretty well as attributes are usually followed by either of those.

10809: fix: don't discard formatting of `use` lines r=Veykril a=iDawer
Use mutable syntax trees in `merge_imports`, `split_imports`. This tries to resolve#9013. But I haven't much managed to simplify code of merging.
Also resolve#9361. It reuses a use tree under the cursor so that comments+indentation are preserved. Merged trees are just appended to the end.
This touches bunch of tests. I removed the sorting of use trees as it needs a proper implementation that takes into account comments and line wrapping. I think it is rustfmt's job or at least until we get a close implementation.

Revert "Fix `impl_trait` function to emit correct ast"
This reverts commit 55a4813151.
Fix `impl_def_from_trait`
It now generates the correct `ast::Impl` using
`generate_trait_impl_text` and parses it to form the right node (copied
from the private fn 'make::ast_from_text').

10563: feat: Make "Generate getter" assist use semantic info r=agluszak a=agluszak
This PR makes "Generate getter" assist use semantic info instead of dealing with types encoded as strings.
Getters for types which are:
- `Copy` no longer return references
- `AsRef<str>` (i.e. `String`) return `&str` (instead of `&String`)
- `AsRef<[T]>` (i.e. `Vec<T>`) return `&[T]` (instead of `&Vec<T>`)
- `AsRef<T>` (i.e. `Box<T>`) return `&T` (instead of `&Box<T>`)
- `Option<T>` return `Option<&T>` (instead of `&Option<T>`)
- `Result<T, E>` return `Result<&T, &E>` (instead of `&Result<T, E>`)
String, Vec, Box and Option were previously handled as special cases.
Closes#10295

10491: Support nested type on replace if let with match r=k-nasa a=k-nasa
## Why
close: https://github.com/rust-analyzer/rust-analyzer/issues/8690
Now, Replacing if-let with match cant't output exhaustive patterns code.
This was because the `else` conversion used specific types (ex. Option, Result) instead of wildcards.
I thought it was more of a problem to generate non-exhaustive patterns than the benefits of using the concrete one.
How about using wildcards in `else`?
Is this change policy acceptable?
## What
- using wildcards on `make_else_arm`
- Change test cases
