Prior to this commit, `str` documented that `get_unchecked` had the precondition that "`begin` must come before `end`". This would appear to prohibit empty slices (i.e. begin == end). In practice, get_unchecked is called often with empty slices. Let's relax the precondition so as to allow them.

Formatting fixes Now that I can actually run `python x.py test src/tools/tidy` locally ... my god it takes a long time to compile when you're on a cellular connection.

… r=nagisa Relax str::get_unchecked precondition to permit empty slicing Prior to this commit, `str` documented that `get_unchecked` had the precondition that "`begin` must come before `end`". This would appear to prohibit empty slices (i.e. begin == end). In practice, get_unchecked is called often with empty slices. Let's relax the precondition so as to allow them.
…cs_replace_chunk_with_windows, r=Dylan-DPC Fix minor error in `MaybeUninit::get_mut()` doc example In the `MaybeUninit::get_mut()` example I wanted to assert that the slice was sorted and mistakenly used `.chunks(2)` rather than `.windows(2)` to assert it, as @ametisf pointed out in rust-lang#65948 (comment) . This fixes it.
…crum Add rustdoc aliases to `ptr::copy` and `ptr::copy_nonoverlapping` This PR adds a [rustdoc alias](https://doc.rust-lang.org/nightly/rustdoc/unstable-features.html#add-aliases-for-an-item-in-documentation-search) to `ptr::copy` and `ptr::copy_nonoverlapping` using the commonly used terms `memcpy` and `memmove`. The motivation for this PR is to improve discoverability for these functions, since I've noticed users overlook these functions on multiple occasions (and they have thus reached for [libc](https://crates.io/crates/libc) without need). Currently std docs state: https://doc.rust-lang.org/nightly/std/ptr/fn.copy_nonoverlapping.html > `copy_nonoverlapping` is semantically equivalent to C's `memcpy`, but with the argument order swapped. https://doc.rust-lang.org/nightly/std/ptr/fn.copy.html > `copy` is semantically equivalent to C's `memmove`, but with the argument order swapped. #### search results before adding a rustdoc alias:   #### after adding `#[doc(alias = "memcpy")]` and `#[doc(alias = "memmove")]`:
