Issue Description:
This code snippet works on OS X but not on Linux.
babt@Swift-TestVM:/usr/include/openssl$ swift
Welcome to Swift version 3.0-dev (LLVM 752e1430fc, Clang 1e6cba3ce3, Swift 56052cfe61). Type :help for assistance.

error: repl.swift:12:37: error: constructing an object of class type 'Self' with a metatype value must use a 'required' initializer
let data = self.dynamicType.init(bytes: &myName, length: myName.utf8.count)
~~~~~~~~~~~~~~~~ ^
Foundation.NSData:2:24: note: selected non-required initializer 'init(bytes:length:)'
public convenience init(bytes: UnsafePointer<Swift.Void>?, length: Int)

The error I'm receiving appears to be correct but this same code works fine on OS X which indicates to me that that initializer on OS X is marked as `required`. Therefore, should the initializer on Linux also be marked as required. Looking at the source, it not currently. Which one is right? If OS X is right (which I hope to be the case), I can prepare a PR with the fix.
