Add action to expand a declarative macro once, inline. Fixes#13598
This commit adds a new r-a method, `expandMacroInline`, which expands the macro that's currently selected. See #13598 for the most applicable issue; though I suspect it'll resolve part of #5949 and make #11888 significantly easier).
The macro works like this:
I have 2 questions before this PR can be merged:
1. **Should we rustfmt the output?** The advantage of doing this is neater code. The disadvantages are we'd have to format the whole expr/stmt/block (since there's no point just formatting one part, especially over multiple lines), and maybe it moves the code around more in weird ways. My suggestion here is to start off by not doing any formatting; and if it appears useful we can decide to do formatting in a later release.
2. **Is it worth solving the `$crate` hygiene issue now?** -- I think this PR is usable as of right now for some use-cases; but it is annoying that many common macros (i.e. `println!()`, `format!()`) can't be expanded further unless the user guesses the correct `$crate` value. The trouble with solving that issue is that I think it's complicated and imperfect. If we do solve it; we'd also need to either change the existing `expandMacro`/`expandMacroInline` commands; provide some option to allow/disallow `$crate` expanding; or come to some other compromise.
fix: generate async delegate methods
Fixes a bug where the generated async method doesn't await the result before returning it.
This is an example of what the output looked like:
```rust
struct Age<T>(T);
impl<T> Age<T> {
pub(crate) async fn age<J, 'a>(&'a mut self, ty: T, arg: J) -> T {
self.0
}
}
struct Person<T> {
age: Age<T>,
}
impl<T> Person<T> {
pub(crate) async fn age<J, 'a>(&'a mut self, ty: T, arg: J) -> T {
self.age.age(ty, arg) // .await is missing
}
}
```
The `.await` is missing, so the return type is `impl Future<Output = T>` instead of `T`
Always permit ConstProp to exploit arithmetic identities
Fixes https://github.com/rust-lang/rust/issues/72751
Initially, I thought I would need to enable operand propagation then do something else, but actually https://github.com/rust-lang/rust/pull/74491 already has the fix for the issue in question! It looks like this optimization was put under MIR opt level 3 due to possible soundness/stability implications, then demoted further to MIR opt level 4 when MIR opt level 2 became associated with `--release`.
Perhaps in the past we were doing CTFE on optimized MIR? We aren't anymore, so this optimization has no stability implications.
r? `@oli-obk`
feat: add the ability to limit the number of threads launched by `main_loop`
## Motivation
`main_loop` defaults to launch as many threads as cpus in one machine. When developing on multi-core remote servers on multiple projects, this will lead to thousands of idle threads being created. This is very annoying when one wants check whether his program under developing is running correctly via `htop`.

## Contribution
This patch introduce the configuration option `rust-analyzer.numThreads` to set the desired thread number used by the main thread pool.
This should have no effects on the performance as not all threads are actually used.

## Demonstration
The following is a snippet of `lunarvim` configuration using my own build.
```lua
vim.list_extend(lvim.lsp.automatic_configuration.skipped_servers, { "rust_analyzer" })
require("lvim.lsp.manager").setup("rust_analyzer", {
cmd = { "env", "RA_LOG=debug", "RA_LOG_FILE=/tmp/ra-test.log",
"/home/jlhu/Projects/rust-analyzer/target/debug/rust-analyzer",
},
init_options = {
numThreads = 4,
},
settings = {
cachePriming = {
numThreads = 8,
},
},
})
```
## Limitations
The `numThreads` can only be modified via `initializationOptions` in early initialisation because everything has to wait until the thread pool starts including the dynamic settings modification support.
The `numThreads` also does not reflect the end results of how many threads is actually created, because I have not yet tracked down everything that spawns threads.
add wrapping/checked/saturating assist
This addresses #13452
I'm not sure about the structure of the code. I'm not sure if it needs to be 3 separate assists, and if that means it needs to be in 3 separate files as well.
Most of the logic is in `util.rs`, which feels funny to me, but there seems to be a pattern of 1 assist per file, and this seems better than duplicating the logic.
Let me know if anything needs changes 😁

Simplify match statement
Add multiple tests
- 1 test for checking `N + 1 + 1` does not unify with `N+1`
- 2 tests for checking that a function that uses two parameters only returns the parameter that
is actually used.
- Check exact repeat predicates
Instead of just switching to a probe, check for different matches, and see how many there are.
If one, unify it, otherwise return true and let it be unified later.
