Added the relevant bits of the great documentation John wrote in clang/docs/PointerAuthentication.rst.  I tried to trim it down to only the general principles and the intrinsics;  some of the discussion around the security model is a little ahead of the rest of the changes, but is still seems fine with these initial changes.
