11399: Fix assoc type shorthand from method bounds r=flodiebold a=flodiebold
In code like this:
```rust
impl<T> Option<T> {
fn as_deref(&self) -> T::Target where T: Deref {}
}
```
when trying to resolve the associated type `T::Target`, we were only
looking at the bounds on the impl (where the type parameter is defined),
but the method can add additional bounds that can also be used to refer
to associated types. Hence, when resolving such an associated type, it's
not enough to just know the type parameter T, we also need to know
exactly where we are currently.
This fixes#11364 (beta apparently switched some bounds around).

11322: Extract function also extracts comments r=Vannevelj a=Vannevelj
Fixes#9011
The difficulty I came across is that the original assist works from the concept of a `ast::StmtList`, a node, but that does not allow me to (easily) represent comments, which are tokens. To combat this, I do a whole bunch of roundtrips: from the `ast::StmtList` I retrieve the `NodeOrToken`s it encompasses.
I then cast all `Node` ones back to a `Stmt` so I can apply indentation to it, after which it is again parsed as a `NodeOrToken`.
Lastly, I add a new `make::` api that accepts `NodeOrToken` rather than `StmtList` so we can write the comment tokens.

11182: fix: don't panic on seeing an unexpected offset r=Veykril a=dimbleby
Intended as a fix, or at least a sticking plaster, for #11081.
I have arranged that [offset()](1ba9a924d7/crates/ide_db/src/line_index.rs (L105-L107)) returns `Option<TextSize>` instead of going out of bounds; other changes are the result of following the compiler after doing this.
Perhaps there's still an issue here - I suppose the server and client have gotten out of sync and that probably shouldn't happen in the first place? I see that https://github.com/rust-analyzer/rust-analyzer/issues/10138#issuecomment-913727554 suggests what sounds like a more substantial fix which I think might be aimed in this direction. So perhaps that one should be left open to cover such things?
Meanwhile, I hope that not-crashing is a good improvement: and I can confirm that it works out just fine in the repro I have at #11081.

11367: minor: Use `compare_exchange_weak` in `limit::Limit::check` r=lnicola a=WaffleLapkin
Not a big deal, but generally loops should use `_weak` version of `compare_exchange`.

This patch makes RA understand `#![recursion_limit = "N"]` annotations.
- `crate_limits` query is moved to `DefDatabase`
- `DefMap` now has `recursion_limit: Option<u32>` field
This allows fetching crate limits like `recursion_limit`. The
implementation is currently dummy and just returns the defaults.
Future work: Use this query instead of the hardcoded constant.
Future work: Actually implement this query by parsing
`#![recursion_limit = N]` attribute.
