rustdoc: Prevent infinite recursion when inlining Cyclic pub-use chains triggered infinite recursion, and this commit adds a hash set to guard against cyclic recursion. This will cause one of the reexports to render as a `pub use` instead of inlining the documentation. Closes #16274 2014-09-23 22:13:56 +00:00			`#![crate_type = "lib"]`
