Merge of the "princeton" branch:
- Define type "block" as "positive" instead of "Z".
- Strengthen mem_unchanged_on so that the permissions are identical,
instead of possibly increasing.
- Move mem_unchanged_on from Events to Memory.Mem.
- Define it in terms of mem_contents rather than in terms of Mem.load.
- ExportClight: try to name temporaries introduced by SimplExpr
- SimplExpr: avoid reusing temporaries between different functions,
instead, thread a single generator through all functions.
