For some reason, I always forget which variants are smaller and which are larger when you derive PartialOrd on an enum. And the wording in the current docs is not entirely clear to me. So, I often end up making a small enum, deriving PartialOrd on it, and then writing a `#[test]` with an assert that the top one is smaller than the bottom one (or the other way around) to figure out which way the deriving goes. So then I figured, it would be great if the standard library docs just had that example, so if I keep forgetting, at least I can figure it out quickly by looking at std's docs.

…tained, r=petrochenkov Fix LLVM libunwind build for non-musl targets Broken in rust-lang#85600. AFAICT, [only musl, mingw, and wasm](https://github.com/rust-lang/rust/blob/673d0db5e393e9c64897005b470bfeb6d5aec61b/compiler/rustc_target/src/spec/crt_objects.rs#L128-L132) should use the “self-contained” logic in rustbuild.
…t, r=RalfJung Add test case for using `slice::fill` with MaybeUninit Adds test for rust-lang#87891 Looks alright? `@RalfJung` Fixes rust-lang#87891
small const generics cleanup
remove redundant / misplaced sentence from docs Removes sentence that seems to have drifted down into the examples section. Luckily, someone already added an explanation of what happens with packed structs back into the initial section of the doc entry and this wayward sentence can likely just be deleted.
…nieu Update outdated docs of array::IntoIter::new.
Update primitive docs for rust 2021. Fixes rust-lang#87701
