Build tools 15.1 with turned on library distribution - cannot compile typealias that is a composition of two protocols where at least one is using primary associated type

[Skoti]

When using build tools 14.3 everything works, but when using 15.1 the following piece of code fails to compile when BUILD_LIBRARY_FOR_DISTRIBUTION is set to YES.

public protocol Test<PrimaryType> {
    associatedtype PrimaryType

    func give() -> PrimaryType
}

public typealias Concrete = Test<Int> & AnyObject

public protocol Factory {
    func concrete() -> any Concrete
}

It looks like a bug was introduced in the new build tools version.

The output error is:

** BUILD FAILED **

excerpt:

error: non-protocol, non-class type 'Test<Int>'
cannot be used within a protocol-constrained type
  func concrete() -> any PatTest.Test<Swift.Int> & Swift.AnyObject
                         ^

I would expect this should compile with no issues.
