Fix#2922: add unknown length as a condition for a type having unknown.
Incorporate reviews:
* Extract some of the const evaluation workings into functions
* Add fixmes on the hacks
* Add tests for impls on specific array lengths (these work!!! 😁)
* Add tests for const generics (indeed we don't support it yet)
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).

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

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

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.
8352: Remove dead legacy macro expansion code r=lnicola a=brandondong
I was investigating some unrelated macro issue when I noticed this dead code. This legacy macro expansion logic was changed in https://github.com/rust-analyzer/rust-analyzer/pull/8128.

8245: Properly resolve intra doc links in hover and goto_definition r=matklad a=Veykril
Unfortunately involves a bit of weird workarounds due to pulldown_cmark's incorrect lifetimes on `BrokenLinkCallback`... I should probably open an issue there asking for the fixes to be pushed to a release since they already exist in the repo for quite some time it seems.
Fixes#8258, Fixes#8238

Bitflags is generally a good dependency -- it's lightweight, well
maintained and embraced by the ecosystem.
I wonder, however, do we really need it? Doesn't feel like it adds much
to be honest.

Only one upgradeable read lock can be handed out at the same time, and
we never acquire a non-upgradeable read lock, so this has no benefit
over just using a write lock in the first place.
8266: Fix generic arguments being incorrectly offset in qualified trait casts r=flodiebold a=Veykril
We reverse the segments and generic args of the lowered path after building it, this wasn't accounted for when inserting the self parameter in `Type as Trait` segments.

7907: Autoderef with visibility r=cynecx a=cynecx
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841.
I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below

Fixes the panics/incorrect injection highlighting of outline module declarations until we figure out a nicer source mapping strategy for attributes.

8065: Better handling of block doc comments r=Veykril a=Veykril
Moves doc string processing to `Attrs::docs`, as we need the indent info from all comments before being able to know how much to strip

8063: couple clippy::complexity fixes r=matklad a=matthiaskrgr
avoid redundant `.into()` calls to convert T into identical T (`let x: String = String::from("hello").into();`)
use `if let Some(x)` instead of `.is_some()` + `.unwrap()`
don't clone Copy types
remove redundant wrapped ?s: `Some(Some(3)?)` can just be `Some(3)`
use `.map(|x| y)` instead of `and_then(|x| Some(y)` on `Option`s
