feature: Create `UnindexedProject` notification to be sent to the client
(Note that this branch contains commits from https://github.com/rust-lang/rust-analyzer/pull/15830, which I'll rebase atop of as needed.)
Based on the discussion in https://github.com/rust-lang/rust-analyzer/issues/15837, I've added a notification and off-by-default toggle to send that notification from `handle_did_open_text_document`. I'm happy to rename/tweak this as needed.
I've been using this for a little bit, and it does seem to cause a little bit more indexing/work in rust-analyzer, but it's something that I'll profile as needed, I think.
feat: Add incorrect case diagnostics for traits and their associated items
Updates incorrect case diagnostic to:
- Check traits and their associated items
- Ignore trait implementations except for patterns in associated function bodies
Also cleans up `hir-ty::diagnostics::decl_check` a bit (mostly to make it a bit more DRY and easier to maintain)
Also fixes: #8675 and fixes: #8225
fix: Recover from missing argument in call expressions
Previously, when parsing an argument list with a missing argument (e.g., `(a, , b)` in `foo(a, , b)`), the parser would stop upon an unexpected token (at the second comma in the example), resulting in an incorrect parse tree.
This commit improves error handling in such cases, ensuring a more accurate parse tree is built.

internal: Update rustc_pattern_analysis dependency
Just bumping the dependency, as I've been making API changes over on the rustc side. More API changes incoming in the coming weeks.
One benefit of this: we no longer abort in the `DeconstructedPat: Debug` impl, which means we can use `tracing` to investigate issues.
Swap Subtree::token_trees from Vec to boxed slice
Performs one of the optimizations suggested in #16325, but a little bit more. Boxed slices guarantee `shrink_to_fit` aswell as saving a pointer width as no capacity has to be stored.
Most of the diff is:
- Changing `vec![]` to `Box::new([])`
- Changing initialize -> fill into fill -> into_boxed_slice
- Working around the lack of an owned iterator or automatic iteration over a `Box<[T]>`
I would like to use my own crate, [small-fixed-array](https://lib.rs/small-fixed-array), although I understand if it isn't mature enough for this. If I'm given the go ahead, I can rework this PR to use it instead.
internal: even more `tracing`
As part of profiling completions, I added some additional spans and moved `TyBuilder::subst_for_def` closer to its usage site (the latter had a small impact on completion performance. Thanks for the tip, Lukas!)
internal: `tracing` improvements and followups
Hi folks! Building on https://github.com/rust-lang/rust-analyzer/pull/16394, I've got a few small tweaks:
- Removed the accidental `mod.rs` usage that I introduced.
- Removed a panic in `pat_analysis.rs`.
- Recorded the event kind in `handle_event` to better distinguish what _kind_ of event is being handled.
- Did a small refactor of `hprof` to have somewhat more linear control flow, and more importantly, write the recorded fields to the output.
The end result is the following:
