Issue Description:

Compiler crash when delegating Collection conformance to another package, using a Collection-wrapping protocol in the other package.

Run swift package update and swift build within MinimalExample to reproduce the crash.

MinimalExample contains

import DataStructures

public struct WrappedIntCollection: CollectionWrapping {
    public let base: [Int]
}

where DataStructures is a module in a separate package that contains

public protocol CollectionWrapping: Collection {
    associatedtype Base: Collection
    var base: Base { get }
}

and the Collection conformance requirements of CollectionWrapping are delegated to Base.
