Don't switch workspace on vfs file changes from libraries
When r-a starts up, it starts switching the workspace before all vfs
events have been processed which causes us to switch workspace multiple
times until all vfs changes have been processed. This scales with the
size of the project and its dependencies. If workspace files from
dependencies as well as the sysroot get loaded, we shouldn't switch
the workspace as those have no impact on the project workspace.

feat: Handle operators like their trait functions in the IDE
Allows hover and goto implementation to work on `?`, indexing brackets, binary operators, prefix operators and `await`. Regarding `await`, hover will continue to show the keyword docs while goto implementation will bring the user to the `poll` function of the `Future` implementation.

There is still the problem that all the diagnostics are cleared, only clearing diagnostics of the relevant workspace isn't easily doable though I think, will have to dig into that

Auto merge of #12837 - DorianListens:dscheidt/generate-enum-data, r=Veykril
feat: support associated values in "Generate Enum Variant" assist
This change adds support for associated values to the "Generate Enum Variant" assist.
I've split the implementation out into 4 steps to make code review easier:
- Add "add_variant" support to the structural ast editing system in `edit_in_place`
- Migrate `generate_enum_variant` to use structural ast editing instead of string manipulation
- Support tuple fields
- Support record fields
Please let me know if I should leave the commits as-is, or squash before merging.

Add syntax fixup for while loops

This is a first iteration to gather some feedback. In particular I'm not sure if the curly braces should be added here, but I couldn't get the test to work without them. Any hints welcome!

Auto merge of #12918 - lowr:fix/doctest-names, r=Veykril
fix: remove whitespaces from doctest names
When rustdoc runs doctests, it removes whitespaces from the tests' path ([code](https://github.com/rust-lang/rust/blob/25bb1c13bd472b75ceebee3b8dcf4dcbc431a8be/src/librustdoc/doctest.rs#L951)). See https://github.com/rust-lang/rust/pull/89422 for details.
Interestingly enough, "Run doctest" has been working without much problem even though rust-analyzer hasn't followed the change. This is because cargo passes the test name to rustdoc via `--test-args` option, and then rustdoc [splits it by whitespace](https://github.com/rust-lang/rust/blob/25bb1c13bd472b75ceebee3b8dcf4dcbc431a8be/src/librustdoc/config.rs#L513-L514); the last element of the split test name **always** matches the test name that rustdoc generates.
However, it may run other tests unexpectedly (to be precise, this has long since been a thing because of the split). Consider the following example:
When you "Run doctest" either of the two, rustdoc considers "U>" one of the test specs and both doctests are run. This patch fixes it by following rustdoc and removing the whitespace from the doctests' name.
Auto merge of #12915 - lnicola:promote-subtree, r=lnicola
internal: Update `xtask promote` and release instructions
Update `xtask` for the subtree workflow. This doesn't explain how to do a `rust -> RA` sync, since that's definitely more involved, but will probably only happen rarely.
Not too happy with the duplication needed for this, but it is what it is. Completions in path qualifiers will have to be filtered properly still, but its better to show too many completions for this than too few for now.
Auto merge of #12877 - zachs18:inline-def-in-macro, r=zachs18
fix: Insert spaces when inlining a function defined in a macro.
(partially) fixes #12860.
This PR (only) addresses the whitespace issue when inlining functions defined in macros.
Additionally, the indentation/spacing is not ideal, but works, e.g.
```rs
macro_rules! define_function {
() => { fn test_function_macro() {
if let Some(3) = 3i32.checked_add(0) {
println!("3 + 0 == 3");
}
} };
}
define_function!();
fn main() {
test_function_macro();
}
// previously became
// ...
fn main() {
ifletSome(3)=3i32.checked_add(0){println!("3 + 0 == 3");};
}
// now becomes
// ...
fn main() {
if let Some(3) = 3i32.checked_add(0){
println!("3 + 0 == 3");
};
}
```
The `self` -> `this` problem[^this] is (probably?) a separate problem that I am also looking into.
[^this]: As mentioned in [my comment on the above issue](https://github.com/rust-lang/rust-analyzer/issues/12860#issuecomment-1193231766), inlining a method defined in a macro does not properly replace `self` with the new local `this`.
Also downmaps tokens inside deriver helpers to the derive expansion
This does not handle the case where multiple derives make use of the same helper name though, unsure how to tackle that yet.
Auto merge of #12858 - fasterthanlime:proc-macro-srv-bin, r=Veykril
Add `rust-analyzer-proc-macro-srv` binary, use it if found in sysroot
This adds a `bin` crate which simply runs `proc_macro_srv::cli::run()` (it does no CLI argument parsing, nothing).
The intent is to build that crate in Rust CI as part of the `dist::Rustc` component, then ship it in the sysroot: it would probably land in something like `~/.rustup/toolchains/nightly-2022-07-23-x86_64-unknown-linux-gnu/libexec/proc-macro-srv-cli`.
This makes https://github.com/rust-lang/rustup/pull/3022 less pressing. (Instead of teaching RA about rustup components, we simply teach it to look in the sysroot via `rustc --print sysroot`. If it can't find `proc-macro-srv-cli`, it falls back to its own `proc-macro` subcommand).
This is closely related to https://github.com/rust-lang/rust-analyzer/issues/12803 (but doesn't close it yet).
Things to address now:
* [ ] What should the binary be named? What should the crate be named? We can pick different names with `[bin]` in the `Cargo.toml`
Things to address later:
* Disable the "multi ABI compatibility scheme" when building that binary in Rust CI (that'll probably happen in `rust-lang/rust`)
* Teaching RA to look in the sysroot
Things to address much, much later:
* Is JSON a good fit here
* Do we want to add versioning to future-proof it?
* Other bikesheds
When built with `--features sysroot` on `nightly-2022-07-23-x86_64-unknown-linux-gnu`, the binary is 7.4MB. After stripping debuginfo, it's 2.6MB. When compressed to `.tar.xz`, it's 619KB.
In a Zulip discussion, `@jyn514` and `@Mark-Simulacrum` seemed to think that those sizes weren't a stopper for including the binary in the rustc component, even before we shrink it down further.
