Fix extract variable assist for subexpression in mutable borrow
This checks if the expression is in a mutable borrow and if so makes the extracted variable `mut`.
Closes#12786
feat: Support the 1.64 nightly proc macro ABI
Should resolve https://github.com/rust-lang/rust-analyzer/issues/12600
Not sure why I thought the Rust version was the same as on beta, that's never the case (but future nightly changes can break the ABI again).
fix: Stack overflows and wrong type inference of associated type shorthands
This fixes `generic_predicates_for_param_query` comparing local IDs that belong to different definitions.
As the query is used in multiple places this fix affects various r-a features when an associated type shorthand and `impl Trait` involved. Notably inference, goto, completion, hover.
Fixes#12484
internal: Record all macro definitions in ItemScope
Fixes https://github.com/rust-lang/rust-analyzer/issues/12100
Doesn't resolve the shadowing issues though, fixing those is gonna be really tricky I believe unless we can come up with a nice scheme to "order" item tree items (using syntax ranges and file ids would be a pain and also a bad idea since that'll require us to potentially reparse files in collection).
Automatically instaciate trivially instaciable structs in "Generate new" and "Fill struct fields"
As proposed in #12535 this PR changes the "Generate new" and "Fill struct fields" assist/diagnostic to instanciate structs with no fields and enums with a single empty variant.
For example:
```rust
pub enum Bar {
Bar {},
}
struct Foo<T> {
a: usize,
bar: Bar,
_phantom: std::marker::PhantomData<T>,
}
impl<T> Foo<T> {
/* generate new */
fn random() -> Self {
Self { /* Fill struct fields */ }
}
}
```
was previously:
```rust
impl<T> Foo<T> {
fn new(a: usize, bar: Bar, _phantom: std::marker::PhantomData<T>) -> Self {
Self { a, bar, _phantom }
}
fn random() -> Self {
Self {
a: todo!(),
bar: todo!(),
_phantom: todo!(),
}
}
}
```
and is now:
```rust
impl<T> Foo<T> {
fn new(a: usize) -> Self {
Self {
a,
bar: Bar::Bar {},
_phantom: std::marker::PhantomData
}
}
fn random() -> Self {
Self {
a: todo!(),
bar: Bar::Bar {},
_phantom: std::marker::PhantomData,
}
}
}
```
I'd be happy about any suggestions.
## TODO
- [x] deduplicate `use_trivial_constructor` (unclear how to do as it's used in two separate crates)
- [x] write tests
Closes#12535
fix: Improve syntax fixup a bit, handle incomplete `if`
- allow appending tokens after a token, not just a node
- allow inserting delimiters (and remove them again)
- fix up `if {}` and `if` without anything following

fix: Support generics in extract_function assist
This change attempts to resolve issue #7636: Extract into Function does not
create a generic function with constraints when extracting generic code.
In `FunctionBody::analyze_container`, we now traverse the `ancestors` in search
of `AnyHasGenericParams`, and attach any `GenericParamList`s and `WhereClause`s
we find to the `ContainerInfo`.
Later, in `format_function`, we collect all the `GenericParam`s and
`WherePred`s from the container, and filter them to keep only types matching
`TypeParam`s used within the newly extracted function body or param list. We
can then include the new `GenericParamList` and `WhereClause` in the new
function definition.
This change only impacts `TypeParam`s. `LifetimeParam`s and `ConstParam`s are
out of scope for this change.
I've never contributed to this project before, but I did try to follow the style guide. I believe that this change represents an improvement over the status quo, but I think it's also fair to argue that it doesn't fully "fix" the linked issue. I'm totally open to merging this as is, or going further to try to make a more complete solution. Also: if there are other unit or integration tests I should add, please let me know where to look!

Fix obsolete config keys
The config keys were drastically reorganized by #12010, but the docs don't reflect the updates, causing inconsistency and confusion. I checked for such obsolete configuration keys and updated to the new one. For reproducibility, I attach a small shell script that I used to examine the old keys. Now the script only detects `cargoExtraArgs` and `overrideCargo`, which originates from other type definition in the code but not from the configuration.

fix: Update 1.63 proc macro ABI to match rustc
This updates us to the ABI used by rustc 1.63.0-beta.5, which will likely be the ABI of the next stable Rust release. It should also work on nightly (for now, but future changes won't be supported until the rustc version is bumped).
