11211: fix: Fix parsing of `#[derive]` paths r=jonas-schievink a=jonas-schievink
Currently this code produces an empty derive path for every `,`, which makes the IDE layer resolve derive paths to the wrong derive macro in the list. Skip `,`s to fix that. (nameres just ignored them, so it didn't cause problems there)

11195: Correctly pass through reference modifiers when extracting a variable r=Veykril a=Vannevelj
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/10034
This will parse the field expression and look at whether it is marked `&` or `&mut` and include a modifier if appropriate. The original issue only mentions `&mut params` but I've found that this issue also occurs for `&mut locals` as well as `¶ms` and `&locals` so I've also added tests for them.
I'd definitely be interested in hearing where I can make my code more idiomatic for Rust.

11201: fix: Fix completions not considering ancestor items for attribute search r=Veykril a=Veykril
Turns out we never filled the `CompletionContext` with the attribute expansion of attributed impls and traits when typing in the assoc items, as we were only considering the assoc item to have an attribute to expand.

11187: Rename and use the 1.55 ABI for 1.54 r=lnicola a=lnicola
It seems that what we used to call the 1.55 ABI was actually introduced in 1.54.

11184: Correctly pass through mutable parameter references when extracting a function r=Veykril a=Vannevelj
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/10277
I have based this investigation based on my understanding of [the Borrowing chapter](https://doc.rust-lang.org/book/ch04-02-references-and-borrowing.html) but I wasn't able to debug the test runs or see it in action in an IDE. I'll try to figure out how to do that for future PRs but for now, the tests seem to confirm my understanding. I'll lay out my hypothesis below.
Here we define the parameters for the to-be-generated function:
7409880a07/crates/ide_assists/src/handlers/extract_function.rs (L882)
Three values in particular are important here: `requires_mut`, `is_copy` and `move_local`. These will in turn be used here to determine the kind of parameter:
7409880a07/crates/ide_assists/src/handlers/extract_function.rs (L374-L381)
and then here to determine what transformation is needed for the calling argument:
7409880a07/crates/ide_assists/src/handlers/extract_function.rs (L383-L390)
which then gets transformed here:
7409880a07/crates/syntax/src/ast/make.rs (L381-L383)
What I believe is happening is that
* `requires_mut` is `false` (it already is marked as mutable),
* `is_copy` is `false` (`Foo` does not implement `Copy`), and
* `move_local` is `false` (it has further usages)
According to the pattern matching in `fn kind()`, that would lead to `ParamKind::SharedRef` which in turn applies a transformation that prepends `&`.
However if I look at the chapter on borrowing then we only need to mark an argument as a reference if we actually own it. In this case the value is passed through as a reference parameter into the current function which means we never had ownership in the first place. By including the additional check for a reference parameter, `move_local` now becomes `true` and the resulting parameter is now `ParamKind::Value` which will avoid applying any transformations. This was further obscured by the fact that you need further usages of the variable or `move_local` would be considered `true` after all.
I didn't follow it in depth but it appears this idea applies for both the generated argument and the generated parameter.
There are existing tests that account for `&mut` values but they refer to local variables for which we do have ownership and as such they didn't expose this issue.

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.
