@bors r+ rollup=never

While unstable, this a "breaking change" for TAITs, so I'd rather this not land in a rollup, so bisection will be easier for the inevitable issues filed.

type alias impl trait: add tests showing that hidden type only outlives lifetimes that occur in bounds

fixes rust-lang#103642

rust-lang#102417 only made sure that hidden types cannot outlive lifetimes other than the ones mentioned on bounds, but didn't allow us to actually infer anything from that.
