rustc-ap-syntax 487.0.0

Automatically published version of the package `syntax` in the rust-lang/rust repository from commit e22b7a3eef962b1314d344ba7b2f27c986320b32 The publishing script for this crate lives at: https://github.com/alexcrichton/rustc-auto-publish
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.

For more information about how these things work in rustc, see the
rustc guide:
