Since we resolved on the call to do the proposed simplification, I've
edited the spec accordingly.

I moved things around a little bit, which I think simplifies things -
all that happens at computed-value time is that units are absolutized.
Serialization then forces simplification.  I've added some notes that,
since the complexity of the math AST isn't observable (because
serialization flattens it), implementations can simplify internally as
well if they want.
