Right now they are handled in `postfix_dot_expr`, but that doesn't allow it to
correctly handle precedence. Integrate it more tightly with the Pratt parser
instead.
Also includes a drive-by fix for parsing `match .. {}`.
Fixes#2242.
2165: ra_assists: Add add_new assist r=matklad a=rep-nop
Adds a new assist to autogenerate a new fn based on the selected struct, excluding tuple structs and unions. The fn will inherit the same visibility as the struct and the assist will attempt to reuse any existing impl blocks that exist at the same level of struct.
Not marking this as closing #1644 since there's a part 2 of adding autocompletion for when someone starts typing `[pub ]fn new(...`

2249: Cleanup hover r=matklad a=kjeremy
Take advantage of classify_name to consolidate multiple hover paths. This isn't quite as clean as I want it to be (`no_fallback` bool is wonky). There's a relationship between `HoverResult` being empty and the range that is a little warty.
Also I noticed that HoverResults are always marked as exact and have been for quite a while... maybe that should be removed in another PR.

2217: Implement FromStr for enum Edition r=matklad a=clemarescx
Just did this as I came across the comment in the code asking for implementing `std::str::FromStr` for `input::Edition`.
Not sure what was meant by "proper error handling" though, `panic!` with a descriptive message might not be it 😅

2200: Add variables to HIR r=matklad a=matklad
Introduce a `hir::Variable`, which should cover locals, parameters and `self`. Unlike `PatId`, variable knows it's owner so it is self-contained, and should be more convenient to use from `ra_ide_api`.
The goal here is to hide more details about `Body` from hir, which should make it easier to move `Body` into `hir_def`. I don't think that `ra_ide_api` intrracts with bodies directly at the moment anyway, but the glue layer is based basically on `ast::BindPat`, which seems pretty brittle.

2205: Implement bulitin line! macro r=matklad a=edwin0cheng
This PR implements bulitin macro `line!` and add basic infra-structure for other bulitin macros:
1. Extend `MacroDefId` to support builtin macros
2. Add a `quote!` macro for simple quasi quoting.
Note that for support others builtin macros, eager macro expansion have to be supported first, this PR not try to handle it. :)

This removes the special casing for the "core" prelude.
Whenever a later dependency also exports a prelude, it will replace
the formerly imported prelude. The utilized prelude then depends
purely on import order.
This adds support for completion and goto definition of
types defined within the "core" crate. The core crate is
added as a dependency to each crate in the project.
The core crate exported it's own prelude. This caused
now all crates to inherit the core crates prelude instead
of the std crates. In order to avoid the problem the
prelude resolution has been changed to overwrite
an already resolved prelude if this was set to a crate
named core - in order to pick a better prelude like std.
Fixes#2199
Adds a new assist to autogenerate a new fn based on the selected struct,
excluding tuple structs and unions. The fn will inherit the same
visibility as the struct and the assist will attempt to reuse any
existing impl blocks that exist at the same level of struct.
2169: MBE: Mapping spans for goto definition r=matklad a=edwin0cheng
Currently, go to definition gives the wrong span in MBE. This PR implement a mapping mechanism to fix it and it could be used for future MBE hygiene implementation.
The basic idea of the mapping is:
1. When expanding the macro, generated 2 `TokenMap` which maps the macro args and macro defs between tokens and input text-ranges.
2. Before converting generated `TokenTree` to `SyntaxNode`, generated a `ExpandedRangeMap` which is a mapping between token and output text-ranges.
3. Using these 3 mappings to construct an `ExpansionInfo` which can map between input text ranges and output text ranges.

Removes nodrop and extra arrayvec
We have an extra crossbeam-queue and crossbeam-utils left but those should
drop once rayon accepts https://github.com/rayon-rs/rayon/pull/704
2179: Use HirDatabase to compute `is_deprecated` r=matklad a=martskins
This PR fixes#2167 by introducing `attributes_query` and adding `fn attrs(&self, def: crate::AttrDef) -> Option<Arc<[Attr]>>;` to the `DefDatabase` trait.
I'm a little concerned about the two spots in `attributes_query` where code is repeated, but I couldn't figure out a way to avoid that, so.. I welcome suggestions 😄

2173: MBE: Add TokenId shift in macro_rules r=matklad a=edwin0cheng
As discussed in #2169 , for fixing duplication TokenId during expansion :
> What we can do here is to re-number the tokens during expansion. Specifically:
> * when we create macro_rules, we note the highest id of the token we have as shift>
> * when we expand macro rules, if we need to output a token from definition, we just re-use its id
> * if we need to output a token from the argument, we increase its id by shift (so it's guaranteed to not to collide with anything from the definition)
> * finally, when we have a HirFileId of the expansion, we can look up the original value of shift and classify node to the arg/def by comparing it's id with shift.
>
This PR implement first 3 points of above solution.

Fixes https://github.com/rust-analyzer/rust-analyzer/issues/2124
I could not move the cursor position out of `let`:
`le<|>t` vs `let<|>`.
Also, please suggest extra test cases.

2160: Set `deprecated` field on `CompletionItem`s r=matklad a=martskins
This PR aims to address #2042 by setting the deprecated field for completion items.
The setting the tags field for LSP 3.15 part still needs fixing, but that one is blocked due to lsp-types not being up to date with 3.15 yet.
