We currently run these in swift-version 4 by default. This caused us to miss some bugs that only occur in swift-version 5 due to initializer changes happening in swift 5. This at least will allow us to catch such issues in the future. NOTE: I am also going to change objc_throwing_initializers.swift in the same way, but after I fix the bugs that adding -swift-version 5 exposes therein (which is actually <rdar://problem/59830255>)
