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.
8463: Support macros in pattern position r=jonas-schievink a=jonas-schievink
This was fairly easy, because patterns are limited to bodies, so almost all changes were inside body lowering.

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.

8443: Rewrite `#[derive]` removal code to be based on AST r=jonas-schievink a=jonas-schievink
We now remove any `#[derive]` before and including the one we want to expand, in the `macro_arg` query.
The same infra will be needed by attribute macros (except we only remove the attribute we're expanding, not any preceding ones).
Part of https://github.com/rust-analyzer/rust-analyzer/issues/8434 (doesn't implement the cfg-expansion yet, because that's more difficult)
8446: Undo path resolution hack for extern prelude r=jonas-schievink a=jonas-schievink
Reverts the change made in https://github.com/rust-analyzer/rust-analyzer/pull/7959
We don't populate the extern prelude for block DefMaps anymore,
so this is unnecessary

8445: `hir_ty` cleanup r=flodiebold a=flodiebold
Move lots of things around within `hir_ty`. Most notably, all the Chalk-related stuff moves from within `traits/` to the top-level, since Chalk isn't purely a "traits thing" anymore.

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.

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.
