ICE: builtin attribute "cfg_attr" not handled by CheckAttrVisitor

[matthiaskrgr]

auto-reduced (treereduce-rust):

#[cfg_attr::skip]
fn main() {}

original:

//@ revisions: feature gated

#![cfg_attr(feature, feature(lazy_type_alias))]
#![allow(incomplete_features)]

type X = Vec<X>;
//[gated]~^ ERROR cycle detected
//[feature]~^^ ERROR: overflow normalizing the type alias `X`

#[cfg_attr::skip]
fn main() { let b: X = b::lazy_type_alias(); }
