Make test harness arguments configurable and not `--nocapture`.
* Added config `runnables.extraTestBinaryArgs` to control the args.
* The default is `--show-output` rather than `--nocapture` to prevent unreadable output when 2 or more tests fail or print output at once.
* Renamed variables in `CargoTargetSpec::runnable_args()` for clarity.
Fixes#12737.
Suggested changelog info:
> New Features

> * add `rust-analyzer.runnables.extraTestBinaryArgs` to configure test harness options when running tests; replaces a previously hard-coded `--nocapture` option.
I'm not sure I made the right choices in vocabulary, between “binary”, “executable”, and “runnable”, and “launch” vs. “execute”, so let me know if I missed something to be consistent with in the naming and documentation.

Use raw-dylib for Windows synchronization functions
Fixes#123999 by using the raw-dylib feature to specify the DLL to load the Windows futex functions from (e.g. [`WaitOnAddress`](https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitonaddress)). This avoids reliance on the import library causing that issue.
With apologies to ``@bjorn3,`` as it's currently necessary to revert this for cranelift.
Don't inline integer literals when they overflow - new attempt
Basically #116633 but I implemented the suggested changes.
Fixes#115423. Fixes#116631.
This is my first contribution to this repo so please let me know if I'm supposed to change something :)
Properly handle emojis as literal prefix in macros
Do not accept the following
```rust
macro_rules! lexes {($($_:tt)*) => {}}
lexes!(🐛"foo");
```
Before, invalid emoji identifiers were gated during parsing instead of lexing in all cases, but this didn't account for macro pre-expansion of literal prefixes.
Fix#123696.
Introduce perma-unstable `wasm-c-abi` flag
Now that `wasm-bindgen` v0.2.88 supports the spec-compliant C ABI, the idea is to switch to that in a future version of Rust. In the meantime it would be good to let people test and play around with it.
This PR introduces a new perma-unstable `-Zwasm-c-abi` compiler flag, which switches to the new spec-compliant C ABI when targeting `wasm32-unknown-unknown`.
Alternatively, we could also stabilize this and then deprecate it when we switch. I will leave this to the Rust maintainers to decide.
This is a companion PR to #117918, but they could be merged independently.

Fixes <https://github.com/rust-lang/rust-analyzer/issues/12737>.
For things with easily pre-checked overflow conditions -- shifts and unsigned subtraction -- write then checked methods in such a way that we stop emitting wrapping versions of them.
For example, today <https://rust.godbolt.org/z/qM9YK8Txb> neither
```rust
a.checked_sub(b).unwrap()
```
nor
```rust
a.checked_sub(b).unwrap_unchecked()
```
actually optimizes to `sub nuw`. After this PR they do.
rustdoc-search: single result for items with multiple paths
Part of #15723
Preview: https://notriddle.com/rustdoc-html-demo-9/reexport-dup/std/index.html?search=hashmap
This change uses the same "exact" paths as trait implementors and type alias inlining to track items with multiple reachable paths. This way, if you search for `vec`, you get only the `std` exports of it, and not the one from `alloc`.
It still includes all the items in the search index so that you can search for them by all available paths. For example, try `core::option` and `std::option`, and notice that the results page doesn't show duplicates, but still shows all the items in their respective crates.
Add support for Arm64EC to the Standard Library
Adds the final pieces so that the standard library can be built for arm64ec-pc-windows-msvc (initially added in #119199)
* Bumps `windows-sys` to 0.56.0, which adds support for Arm64EC.
* Correctly set the `isEC` parameter for LLVM's `writeArchive` function.
* Add `#![feature(asm_experimental_arch)]` to library crates where Arm64EC inline assembly is used, as it is currently unstable.
