Issue Description:

Reproducer using latest master or 5.3 snapshot:

@propertyWrapper
public struct UserDefault<T> {
    init(_ key: String, defaultValue: T) {}
    public var wrappedValue: T {
        get { fatalError() }
        set {}
    }
}

public struct AppUserDefaults {
    /*range start*/@UserDefault("user_region", defaultValue: "US")
    public static var region: String/*range end*/
}

Trace:

1.  While walking into decl 'AppUserDefaults' (at /private/tmp/sdsdfsddsfds/sdsdfsddsfds/main.swift:17:8)
