Distinguish two kinds of nonterminating behaviors: silent divergence
and reactive divergence. As a consequence:
- Removed the Enilinf constructor from traceinf (values of traceinf
type are always infinite traces).
- Traces are now uniquely defined.
- Adapted proofs big step -> small step for Clight and Cminor accordingly.
- Strengthened results in driver/Complements accordingly.
- Added common/Determinism to collect generic results about
deterministic semantics.
