This fixes a case where the Swift-variadic and C-varargs versions of various initializers were superseding each other <rdar://problem/16801456>. It also uncovered some more cases where we weren't getting quite the right semantics for factory-methods-as-initializers, which are also fixed here. Swift SVN r18010
