6251: Semantic Highlight: Add Callable modifier for variables r=matklad a=GrayJack
This PR added the `HighlightModifier::Callable` variant and assigned it to variables and parameters that are fn pointers, closures and implements FnOnce trait.
This allows to colorize these variables/parameters when used in call expression.
6310: Rewrite algo::diff to support insertion and deletion r=matklad a=Veykril
This in turn also makes `algo::diff` generate finer diffs(maybe even minimal diffs?) as insertions and deletions aren't always represented as as replacements of parent nodes now.
Required for #6287 to go on.

6339: Diagnose #[cfg]s in bodies r=matklad a=jonas-schievink
This PR threads diagnostics through body lowering using the `BodySourceMap`, and emits `InactiveCode` diagnostics for expressions, statements, and match arms that are `#[cfg]`d out.

Unfortunately I ran into https://github.com/rust-analyzer/rust-analyzer/issues/4058 while testing this on https://github.com/nrf-rs/nrf-hal/, so I didn't see much of it in action yet, but it does seem to work.

6326: hide paramater inlay hints for cloned vars if applicable r=SomeoneToIgnore a=Veykril
This causes `foo.clone()` parameters to be handled as if they were just `foo` parameters for inlay hint logic.

6320: Textmate grammar: prevent line comments from breaking block comments (closes#6281) r=matklad a=dustypomerleau
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/6281.
Previously, line comments were able to break block comments by essentially commenting out the closing `*/`, resulting in a never-ending comment. This PR splits block comments into a separate repository group to fix this problem.
Since the comment scopes also include ignored parameters and inferred types, I've added the change proposed by @bnjjj in https://github.com/rust-analyzer/rust-analyzer/pull/6317, in order to close https://github.com/rust-analyzer/rust-analyzer/issues/6311 as well.
6321: Fix opening module documentation opening parent documentation instead r=matklad a=zacps

this, but at the same time I don't really want to rewrite it right
now...

6307: Add whitelist of safe intrinsics r=frazar a=frazar
This PR should fix#5996, where intrinsic operations where all marked as unsafe.
I'm rather new to this codebase, so I might be doing something *very* wrong. Please forgive me!
In particular, I'm not sure how to "check that we are in extern `rust-intrinsics`" as mentioned [in this comment](https://github.com/rust-analyzer/rust-analyzer/issues/5996#issuecomment-709234802).

6172: Add qualify path assist r=matklad a=Veykril
This implements a `qualify_path` assist which works quite similar to the `auto_import` assist but instead of adding imports to the file it well, qualifies the path. This PR also moves out the `AutoImportAssets` struct and functions from `auto_import` into a utils submodule as most of this is now shared between `auto_import` and `qualify_path`.
Changes made to `AutoImportAssets` are solely in its `search_for_imports` function which now takes a prefixed parameter to discern between using `find_use_path_prefixed` and `find_use_path` as the former is the required behavior by `auto_import` and the latter by this assist.
For missing imported traits instead of importing this will qualify the path with a trait cast as in:
```rust
test_mod::TestStruct::TEST_CONST<|>
```
becomes
```rust
<test_mod::TestStruct as test_mod::TestTrait>::TEST_CONST
```
and for trait methods ideally it would do the following:
```rust
let test_struct = test_mod::TestStruct {};
test_struct.test_meth<|>od()
```
becomes
```rust
let test_struct = test_mod::TestStruct {};
test_mod::TestTrait::test_method(&test_struct)
```
Fixes#4124.

6299: Diagnose items that are #[cfg]d out r=jonas-schievink a=jonas-schievink

Declaration names sounds like a name of declaration -- something you
can use for analysis. It empathically isn't, and is just a label
displayed in various UI. It's important not to confuse the two, least
we accidentally mix semantics with UI (I believe, there's already a
case of this in the FamousDefs at least).
The proper fix I think is:
* move rust-lang/rust library crates to a separate workspace
* when packaging rust-src component, vendor sources of external deps
This errro specifically:
Updating crates.io index
error: failed to select a version for the requirement `ra_ap_stdx = "^0.0.0"`

6246: Follow symlinks when walking project trees r=lnicola a=dfoxfranke
Fixes#3691.
~~WIP pending further testing~~:
- [X] Verify that symlinked files get indexed.
- [x] Verify that files in symlinked directories get indexed.
- [x] Verify that inotify events are properly received and handled when the target of a symlink resides outside the project tree.

6220: implement binary operator overloading type inference r=flodiebold a=ruabmbua
Extend type inference of *binary operator expression*, by adding support for operator overloads.
Before this merge request, the type inference of binary expressions could only resolve operations done on built-in primitive types. This merge requests adds a code path, which is executed in case the built-in inference could not get any results. It resolves the proper operator overload trait in *core::ops* via lang items, and then resolves the associated *Output* type.
```rust
struct V2([f32; 2]);
#[lang = "add"]
pub trait Add<Rhs = Self> {
/// The resulting type after applying the `+` operator.
type Output;
/// Performs the `+` operation.
#[must_use]
fn add(self, rhs: Rhs) -> Self::Output;
}
impl Add<V2> for V2 {
type Output = V2;
fn add(self, rhs: V2) -> V2 {
let x = self.0[0] + rhs.0[0];
let y = self.0[1] + rhs.0[1];
V2([x, y])
}
}
fn test() {
let va = V2([0.0, 1.0]);
let vb = V2([0.0, 1.0]);
let r = va + vb; // This infers to V2 now
}
```
There is a problem with operator overloads, which do not explicitly set the *Rhs* type parameter in the respective impl block.
**Example:**
```rust
impl Add for V2 {
type Output = V2;
fn add(self, rhs: V2) -> V2 {
let x = self.0[0] + rhs.0[0];
let y = self.0[1] + rhs.0[1];
V2([x, y])
}
}
```
In this case, the trait solver does not realize, that the *Rhs* type parameter is actually self in the context of the impl block. This stops type inference in its tracks, and it can not resolve the associated *Output* type.
I guess we can still merge this back, because it increases the amount of resolved types, and does not regress anything (in the tests).
