Backed out changeset b6c206049d8a
The nvmemmory library depends on a modification to qemu; this change
is therefore backed out in order to allow NVM functionality to be
merged into graphics-phase-3 by transplanting individual commits.
Examples of classes that implement special operators (see reference manual):

(For straightforward examples of basic class features, such as use of
methods and inheritance, see the library code.)
