rustc-ap-rustc_attr 723.0.0

Automatically published version of the package `rustc_attr` in the rust-lang/rust repository from commit 376ec9487eb6fe10068c49a3a74b1b1ff12c4c79 The publishing script for this crate lives at: https://github.com/alexcrichton/rustc-auto-publish 
//! Functions and types dealing with attributes and meta items.
//!
//! FIXME(Centril): For now being, much of the logic is still in `rustc_ast::attr`.
//! The goal is to move the definition of `MetaItem` and things that don't need to be in `syntax`
//! to this crate.
