This increases the size of some important types, such as `ast::Expr` and `mir::Statement`. However, it drastically reduces how much the interner is used, and the fields are more natural sizes that don't require bit operations to extract. As a result, instruction counts drop across a range of workloads, by as much as 12% for incremental "check" builds of `script-servo`. Peak memory usage goes up a little for some cases, but down by more for some other cases -- as much as 18% for non-incremental builds of `packed-simd`. The commit also: - removes the `repr(packed)`, because it has negligible effect, but can cause undefined behaviour; - replaces explicit impls of common traits (`Copy`, `PartialEq`, etc.) with derived ones.
It is now exactly equivalent to lookup_char_pos.
Implicit promotion on the other hand has very strict rules on what may be done
- Make links relative. - Adjust links from old 2018-edition book. - Fix broken link in `let` docs.
This commit implements the `{read,write}_vectored` methods on more types
in the standard library, namely:
* `std::fs::File`
* `std::process::ChildStd{in,out,err}`
* `std::io::Std{in,out,err}`
* `std::io::Std{in,out,err}Lock`
* `std::io::Std{in,out,err}Raw`
Where supported the OS implementations hook up to native support,
otherwise it falls back to the already-defaulted implementation.
It's useful to see the biggest variants first.

remove lookup_char_pos_adj It is now exactly equivalent to lookup_char_pos.
…k, r=ehuss Copy book.toml unstable book generator Solves rust-lang#59554 and adds a book title to the unstable book. I assume that [copy_recursive](https://github.com/rust-lang/rust/blob/acd8dd6a50d505057a7d7ad8d0d7a4c2bd274200/src/tools/unstable-book-gen/src/main.rs#L105) will take files regardless of their type (`.md` or `.toml`). Although I had a hard time time testing it. A second pair of eyes is definitely needed.
Limit dylib symbols This makes `windows-gnu` match the behavior of `windows-msvc`. It probably doesn't make sense to export these symbols on other platforms either.
Retire `IsNotConst` naming This naming scheme caused a lot of confusion lately (including ICEs) due to misrefactored code. Also clean up the initialization code for said flag. r? @eddyb previous discussions: rust-lang#58784 (comment) rust-lang#58403 (comment)

Use SecRandomCopyBytes instead of /dev/urandom on MacOS SecRandomCopyBytes is [available since MacOS 10.7](https://developer.apple.com/documentation/security/1399291-secrandomcopybytes?language=objc) which is the minimum supported version and which was suggested in rust-lang#58901 (comment) is the earliest version currently in use. This matches the behaviour of other platforms which have a random number generator syscall available.
