Overhaul keyword handling The compiler's list of keywords has some problems. - It contains several items that aren't keywords. - The order isn't quite right in a couple of places. - Some of the names of predicates relating to keywords are confusing. - rustdoc and rustfmt have their own (incorrect) versions of the keyword list. - `AllKeywords` is unnecessarily complex. r? ```@jieyouxu``` |

The rustc_ast crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).
For more information about how these things work in rustc, see the rustc dev guide:
