I think this code is getting L0, not L1 cache size, if I'm reading the Intel manual right. (I might not be.) Either way, the code comment and the printed message should match, whichever way is right. :)

…ocs, r=Mark-Simulacrum Document clippy on nightly-rustc Adding Clippy's docs to nightly-rustc, based on commit 01cf0bd. This PR only adds `clippy_utils` to the documentation. I've decided to only document one crate for now, as `clippy_lints` etc. contain very specific and undocumented functions which aren't really reusable. I'm guessing that they would mostly clutter up the search results with little benefit. `./x.py --stage 1 doc src/tools/clippy` if working fine now after the help that ``@jyn514`` and ``@ehuss`` have provided. A big THANK YOU to them!

Add JoinHandle::is_running.
This adds:
```rust
impl<T> JoinHandle<T> {
/// Checks if the the associated thread is still running its main function.
///
/// This might return `false` for a brief moment after the thread's main
/// function has returned, but before the thread itself has stopped running.
pub fn is_running(&self) -> bool;
}
```
The usual way to check if a background thread is still running is to set some atomic flag at the end of its main function. We already do that, in the form of dropping an Arc which will reduce the reference counter. So we might as well expose that information.
This is useful in applications with a main loop (e.g. a game, gui, control system, ..) where you spawn some background task, and check every frame/iteration whether the background task is finished to .join() it in that frame/iteration while keeping the program responsive.
