Merge #2409

2409: Don't #[allow(type_alias_bounds)]. r=kvark a=eddyb

rust-lang/rust#54090 will fix false positives (not relevant here) and make it an error in the upcoming Rust 2018 edition, which means that if you want to migrate to Rust 2018, it shouldn't be ignored.

See also rust-lang/rust#49441 (comment) for the decision and some background.
