8432: decl_check: consider outer scopes' allows r=jonas-schievink a=lf-
Fix#8417. Also makes it less noisy about no_mangle annotated stuff the
user can do nothing about.
Note: this still is broken with bitfield! macros. A repro in an ignore
test is included here. I believe this bug is elsewhere, and I don't
think I can work around it here.
I would like help filing the remaining bug, as it does actually affect
users, but I don't know how to describe the behaviour (or even if it
is unintended).

8415: Fix faulty assertion when extracting function with macro call r=matklad a=brandondong
**Reproduction:**
```rust
fn main() {
let n = 1;
let k = n * n;
dbg!(n);
}
```
1. Select the second and third lines of the main function. Use the "Extract into function" code assist.
2. Panic occurs in debug, error is logged in release: "[ERROR ide_assists::handlers::extract_function] assertion failed: matches!(path, ast :: Expr :: PathExpr(_))".
3. Function generates successfully on release where the panic was bypassed.
```rust
fn fun_name(n: i32) {
let k = n * n;
dbg!(n);
}
```
**Cause:**
- The generated function will take `n` as a parameter. The extraction logic needs to search the usages of `n` to determine whether it is used mutably or not. The helper `path_element_of_reference` is called for each usage but the second usage is a macro call and fails the `Expr::PathExpr(_)` match assertion.
- The caller of `path_element_of_reference` does implicitly assume it to be a `Expr::PathExpr(_)` in how it looks at its parent node for determining whether it is used mutably. This logic will not work for macros.
- I'm not sure if there are any other cases besides macros where it could be something other than a `Expr::PathExpr(_)`. I tried various examples and could not find any.
**Fix:**
- Update assertion to include the macro case.
- Add a FIXME to properly handle checking if a macro usage requires mutable access. For now, return false instead of running the existing logic that is tailored for `Expr::PathExpr(_)`'s.

Conceptually, using a *message* here is wrong, because this is a
"status", rather than "point in time" thing. But statuses are an LSP
extension, while messages are stable. As a compromise, send message only
for more critical `metadata` failures, and only once per state change.
This condition should always be true for *valid* code, but of course
there might be invalid code or things that we can't currently resolve.
Fixes#8464.

8436: Fix extract function's mutability of variables outliving the body r=matklad a=brandondong
**Reproduction:**
```rust
fn main() {
let mut k = 1;
let mut j = 2;
j += 1;
k += j;
}
```
1. Select the first to third lines of the main function. Use the "Extract into function" code assist.
2. The output is the following which does not compile because the outlived variable `k` is declared as immutable:
```rust
fn main() {
let (k, j) = fun_name();
k += j;
}
fn fun_name() -> (i32, i32) {
let mut k = 1;
let mut j = 2;
j += 1;
(k, j)
}
```
3. We would instead expect the output to be:
```rust
fn main() {
let (mut k, j) = fun_name();
k += j;
}
```
**Fix:**
- Instead of declaring outlived variables as immutable unconditionally, check for any mutable usages outside of the extracted function.

8406: Improve indexing of impls r=flodiebold a=flodiebold

Store impls for e.g. &Foo with the ones for Foo instead of the big
"other" bucket. This can improve performance and simplifies the HIR impl
search a bit.
If we get lifetime variables back in autoderef, just immediately replace
them by static lifetimes for now. Method resolution doesn't really deal
correctly with new variables being introduced (this needs to be fixed
more properly).
This fixes `rust-analyzer analysis-stats --with-deps` crashing in the RA
repo.

8419: Move hir_ty to Chalk IR r=flodiebold a=flodiebold
Closes#8313.
There's some further cleanups to do:
- we're still using our `TypeWalk` in lots of places (not for mutating/folding though, just for walking)
- we're still using our own canonicalization and unification and our `InferenceTable`
- ~`ToChalk` still exists and gets called, it's just the identity in most cases now (I'll probably clean those up before merging this)~

I'd prefer getting rid of it, but it's used in the impl search and not
super easy to replace there (I think ideally the impl search would do
proper unification, but that's a bit more complicated).

8397: Return proper error code when server is loading r=matklad a=ceronman
When requests are made to rust-analyzer and the server is still loading, a response error is returned with the code `ContentModified` and text `"Rust Analyzer is still loading..."`. This error code doesn't seem to be the more appropriate for this situation. Using `ServerNotInitialized` seems better.
As this is such a small change, I have not created an issue for it.

8371: Don't use HirDisplayWrapper when displaying SourceCode r=matklad a=Veykril
The issue was basically that when displaying for `DisplayTarget::SourceCode` some `hir_fmt` functions would create `HirDisplayWrapper`s which would then `fmt` these triggering the Display panic since `fmt::Display` can't fail the same way as `HirDisplay`. Simple fix is to just use `hir_fmt` directly. Should probably write that down somewhere in source, looking for a good spot to put that right now.

8364: Memory usage improvements r=jonas-schievink a=alexmaco
These are mostly focused on splitting up enum variants with large size differences between variants by `Box`-ing things up.
In my testing this reduces the memory usage somewhere in the low percentages, even though the measurements are quite noisy.
Co-authored-by: Alexandru Macovei <alexnmaco@gmail.com>
Rationale: only a minority of variants used almost half the size.
By keeping large members (especially in Option) behind a box
the memory cost is only payed when the large variants are needed.
This reduces the size Vec<Expr> needs to allocate.

- don't shift in/out for Chalk mapping (we want to have the same

shouldn't matter much)
- do shift in when lowering a `fn()` type

This adds a "Convert Into to From" assist, useful since clippy has
recently started adding lints on every `Into`.
It covers converting the signature, and converting any `self`/`Self`
references within the body.
It does assume that every instance of `Into` can be converted to a
`From`, which I _think_ is the case now. Let me know if there's
something I'm not thinking of and I can try and make it smarter.
