Reviewed by Myles C. Maxfield.

Add serialization support for override declarations. Notice that we temporarily
disable the mangling of globals, which ironically wasn't being used yet, but
requires notifying the API about the mangling. I will be implementing that next
and will re-enable the mangling.
