This patch makes RA understand `#![recursion_limit = "N"]` annotations.
- `crate_limits` query is moved to `DefDatabase`
- `DefMap` now has `recursion_limit: Option<u32>` field
11145: feat: add config to use reasonable default expression instead of todo! when filling missing fields r=Veykril a=bnjjj
Use `Default::default()` in struct fields when we ask to fill it instead of putting `todo!()` for every fields
before:
```rust
pub enum Other {
One,
Two,
}
pub struct Test {
text: String,
num: usize,
other: Other,
}
fn t_test() {
let test = Test {<|>};
}
```
after:
```rust
pub enum Other {
One,
Two,
}
pub struct Test {
text: String,
num: usize,
other: Other,
}
fn t_test() {
let test = Test {
text: String::new(),
num: 0,
other: todo!(),
};
}
```

10877: feat: make hightlighting linear r=matklad a=matklad
In https://youtu.be/qvIZZf5dmTE, we've noticed that AstIdMap does a
linear lookup when going from SyntaxNode to Id. This leads to
accidentally quadratic overall performance. Replace linear lookup with a
O(1) hashmap lookup.
Future work: don't duplicate `SyntaxNodePtr` in `AstIdMap` and switch to
"call site dependency injection" style storage (eg, store a
`HashSet<ErasedFileAstId>`).
See the explanation of the work here on YouTube :-)
As you can see from then benchmark results, this doesn't actually make analysis stats fastre. I am a bit mystified as to why this is happening to be honest.

I think we probably should merge the first commit here, but not the second.

10704: internal: Short-circuit `descend_into_macros_single` r=Veykril a=Veykril
There is no need to descend everything if all we are interested in is the first mapping.
This bring `descend_into_macros` timing in highlighting in `rust-analyzer/src/config.rs` from `154ms - descend_into_macros (2190 calls)` to `24ms - descend_into_macros (2190 calls)` since we use the single variant there(will regress once we want to highlight multiple namespaces again though).

10603: fix: Don't resolve attributes to non attribute macros r=Veykril a=Veykril
Also changes `const`s to `static`s for `Limit`s as we have interior mutability in those(though only used with a certain feature flag enabled).

10387: Move `IdxRange` into la-arena r=Veykril a=arzg
Currently, `IdxRange` (named `IdRange`) is located in `hir_def::item_tree`, when really it isn’t specific to `hir_def` and could become part of la-arena. The rename from `IdRange` to `IdxRange` is to maintain consistency with the naming convention used throughout la-arena (`Idx` instead of `Id`, `RawIdx` instead of `RawId`). This PR also adds a few new APIs to la-arena on top of `IdxRange` for convenience, namely:
- indexing into an `Arena` by an `IdxRange` and getting a slice of values back
- creating an `IdxRange` from an inclusive range
Currently this PR also exposes a new `Arena::next_idx` method to make constructing inclusive`IdxRange`s using `IdxRange::new` easier; however, it would in my opinion be better to remove this as it allows for easy creation of out-of-bounds `Idx`s, when `IdxRange::new_inclusive` mostly covers the same use-case while being less error-prone.
I decided to bump the la-arena version to 0.3.0 from 0.2.0 because adding a new `Index` impl for `Arena` turned out to be a breaking change: I had to add a type hint in `crates/hir_def/src/body/scope.rs` when one wasn’t necessary before, since rustc couldn’t work out the type of a closure parameter now that there are multiple `Index` impls. I’m not sure whether this is the right decision, though.

I don't like our macro tests -- they are brittle and don't inspire
confidence. I think the reason for that is that we try to unit-test
them, but that is at odds with reality, where macro expansion
fundamentally depends on name resolution.
Consider these expples
{ 92 }
async { 92 }
'a: { 92 }
#[a] { 92 }
Previously the tree for them were
BLOCK_EXPR
{ ... }
EFFECT_EXPR
async
BLOCK_EXPR
{ ... }
EFFECT_EXPR
'a:
BLOCK_EXPR
{ ... }
BLOCK_EXPR
#[a]
{ ... }
As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers
BLOCK_EXPR
STMT_LIST
{ ... }
BLOCK_EXPR
async
STMT_LIST
{ ... }
BLOCK_EXPR
'a:
STMT_LIST
{ ... }
BLOCK_EXPR
#[a]
STMT_LIST
{ ... }
FragmentKind played two roles:
* entry point to the parser
* syntactic category of a macro call
These are different use-cases, and warrant different types. For example,
macro can't expand to visibility, but we have such fragment today.
This PR introduces `ExpandsTo` enum to separate this two use-cases.
I suspect we might further split `FragmentKind` into `$x:specifier` enum
specific to MBE, and a general parser entry point, but that's for
another PR!
