use vec![] instead of Vec::new() + push()
avoid redundant clones
use chars instead of &str for single char patterns in ends_with() and starts_with()
allocate some Vecs with capacity to avoid unneccessary resizing
7966: Diagnose files that aren't in the module tree r=jonas-schievink a=jonas-schievink
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/6377
I'm not sure if this is the best way to do this. It will cause false positives for all `include!`d files (though I'm not sure how much IDE functionality we have for these).

7795: Show docs on hover for keywords and primitives r=matklad a=Veykril
It's a bit annoying that this requires the `SyntaxNode` and `Semantics` to be pulled through `hover_for_definition` just so we can get the `std` crate but I couldn't think of a better way.

7335: added region folding r=matklad a=LucianoBestia
Regions of code that you'd like to be folded can be wrapped with `// #region` and `// #endregion` line comments.
This is called "Region Folding". It is originally available for many languages in VSCode. But Rust-analyzer has its own folding function and this is missing.
With this Pull Request I am suggesting a simple solution.
The regions are a special kind of comments, so I added a bit of code in the comment folding function.
The regex to match are: `^\s*//\s*#?region\b` and `^\s*//\s*#?endregion\b`.
The number of space characters is not important. There is an optional # character. The line can end with a name of the region.
Example:
```rust
// 1. some normal comment
// region: test
// 2. some normal comment
calling_function(x,y);
// endregion: test
```
I added a test for this new functionality in `folding_ranges.rs`.
Please, take a look and comment.
I found that these exact regexes are already present in the file `language-configuration.json`, but I don't find a way to read this configuration. So my regex is hardcoded in the code.
7691: Suggest name in extract variable r=matklad a=cpud36
Generate better default name in extract variable assist as was mentioned in issue #1587
# Currently supported
(in order of declining precedence)
1. Expr is argument to a function; use corresponding parameter name
2. Expr is result of a function or method call; use this function/method's name
3. Use expr type name (if possible)
4. Fallback to `var_name` otherwise
# Showcase
# Questions
* Should we more aggressively strip known types? E.g. we already strip `&T -> T`; should we strip `Option<T> -> T`, `Result<T, E> -> T`, and others?
* Integers and floats use `var_name` by default. Should we introduce a name, like `i`, `f` etc?
* Can we return a list and suggest a name when renaming(like IntelliJ does)?
* Should we add counters to remove duplicate variables? E.g. `type`, `type1`, type2`, etc.

7778: Fix lowering trailing self paths in UseTrees r=Veykril a=Veykril
Noticed that hovering over `self` in a use tree like `use foo::bar::{self}` showing documentation and such for the current module instead of `bar`.

7732: Don't lower TypeBound::Lifetime as GenericPredicate::Error r=flodiebold a=Veykril
Basically we just discard the typebound for now instead when lowering to `GenericPredicate`. I think this shouldn't have any other side effects?
Fixes #7683(hopefully for real this time)
I also played around with introducing `GenericPredicate::LifetimeOutlives` and `GenericPredicate::TypeOutlives`(see b9d6904845) but that won't fix this issue(at least not for now) due to lifetime predicate mismatches when resolving methods so I figure this is a good way to fix it for now.

7699: Implement ast::AstNode for NameLike and move it to node_ext r=matklad a=Veykril
With this `search`(and 2 other modules) don't necessarily go through 3 calls of `find_node_at_offset_with_descend` to find the correct node. Also makes the code that searches for NameLikes a bit easier on the eyes imo, though that can be fixed with just a helper function as well so its not that relevant.
