0dfa6ff3be Avoid cycles from projection bounds
Only check the own predicates of associated types when confirming
projection candidates.
Also consider implied bounds when comparing trait and impl methods.

596d6c4b3b Avoid cycle with projections from object types
Normalizing `<dyn Iterator<Item = ()> as Iterator>::Item` no longer
requires selecting `dyn Iterator<Item = ()>: Iterator`. This was
previously worked around by using a special type-folder to normalize
things.

34e5a4992c Normalize projection bounds when considering candidates
This unfortunately requires some winnowing hacks to avoid
now ambiguous candidates.
