Draft JEP Announcement: "Computed Constants"

[Brian Goetz]

One thing that may not be obvious about this work is that what it 
effectively does is provide a supported, public, specified means to 
expose the functionality that is now restricted to internal JDK use via 
`@Stable`.  (So computed constants is-to @Stable as VarHandles are to 
Unsafe::{get,put}Xxx.)
