18bf278c25 Handle associated type shorthand (T::Item)
This is only allowed for generic parameters (including `Self` in traits), and
special care needs to be taken to not run into cycles while resolving it,
because we use the where clauses of the generic parameter to find candidates for
the trait containing the associated type, but the where clauses may themselves
contain instances of short-hand associated types.

In some cases this is even fine, e.g. we might have `T: Trait<U::Item>, U:
Iterator`. If there is a cycle, we'll currently panic, which isn't great, but
better than overflowing the stack...

1862: Assoc item resolution refactoring (again) r=flodiebold a=flodiebold

This is #1849, with the associated type selection code removed for now. Handling cycles there will need some more thought.

fe1dfd2b20 Refactor some more
Type-relative paths (`<T>::foo`) also need to work in type context, for example
`<T>::Item` is legal. So rather than returning the type ref from the resolver
function, just check it before.

for the segments before the last instead of replicating it.

913ab1ec0a Resolve assoc types on type parameters
E.g. `fn foo<T: Iterator>() -> T::Item`. It seems that rustc does this only for
type parameters and only based on their bounds, so we also only consider traits
from bounds.
