Split out the things that are really specific to Swift 3 into a new closures_swift3.swift. In the process I found that two things that should compile without error under -swift-version 4 do not, so those tests are currently in closures_swift3.swift and I have opened new bugs for the issues: https://bugs.swift.org/browse/SR-5791 https://bugs.swift.org/browse/SR-5792
