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.
