10375: minor: Use SmallVec<[_; 1]> in `descend_into_macros_impl` r=Veykril a=Veykril
A lot of descends don't actually descend in which case we don't wanna allocate

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
{ ... }
Originally we tried to maintain the invariant that `{}` always match.
That is, that in the parse tree the pair of corresponding `{}` is always
first and last tokens of some nodes.
We had the code to validate that, but apparently it's been broken for
**years** since we introduced tokens/nodes split. Fixing it now makes
some tests fail.
It's unclear if we want to keep this invariant: there's a strong
motivation for breaking it in the following case:
```
use std::{ // unclosed paren
fn main() {
}
} // don't actually want to pair up this with the one from `use`
```
So let's fix the code, but disable it for the time being
Previously we swapped to events in the buffer, but that might be wrong
if there aer `forward_parent` links pointing to the swapped-out node.
Let's do the same via parent links instead, keeping the nodes in place
10334: Give rustfmt spawn error context. r=jonas-schievink a=aDotInTheVoid
This mean if you misconfigure to
```json
{
"rust-analyzer.rustfmt.overrideCommand": [
"./nonono"
]
}
```
The error message is
```
[Error - 17:54:33] Request textDocument/formatting failed.
Message: Failed to spawn "./nonono"
Code: -32603
```
instead of
```
[Error - 17:56:12] Request textDocument/formatting failed.
Message: No such file or directory (os error 2)
Code: -32603
```
I'm not sure how to test this, or if it needs a test.

10105: RfC: Use `todo!()` instead of `()` for missing fields r=jonas-schievink a=jo-so
Most commonly a field of a struct can be initialized with its default value than an empty tuple.

10332: minor: Allow overwriting RUST_BACKTRACE for the server manually r=jonas-schievink a=Veykril
Trying to figure out why we aren't getting backtraces for windows builds from CI, this let's one set the backtraces to `FULL`
