bors 3f92e8d898 Auto merge of #46455 - petrochenkov:pimpl, r=nikomatsakis 
syntax: Rewrite parsing of impls

Properly parse impls for the never type `!`
Recover from missing `for` in `impl Trait for Type`
Prohibit inherent default impls and default impls of auto traits (https://github.com/rust-lang/rust/issues/37653#issuecomment-348687794, https://github.com/rust-lang/rust/issues/37653#issuecomment-348688785)
Change wording in more diagnostics to use "auto traits"
Fix some spans in diagnostics
Some other minor code cleanups in the parser
Disambiguate generics and qualified paths in impls (parse `impl <Type as Trait>::AssocTy { ... }`)
Replace the future-compatibility hack from https://github.com/rust-lang/rust/pull/38268 with actually parsing generic parameters
Add a test for https://github.com/rust-lang/rust/issues/46438

README.md

NB: This crate is part of the Rust compiler. For an overview of the compiler as a whole, see the README.md file found in librustc.

The syntax crate contains those things concerned purely with syntax – that is, the AST ("abstract syntax tree"), parser, pretty-printer, lexer, macro expander, and utilities for traversing ASTs.
