Merge branch 'named-structs'
- Switch CompCert C / Clight AST of composite types (structs and unions) from a structural representation to a nominal representation, closer to concrete syntax. - This avoids algorithmic inefficiencies due to the structural representation. - Closes PR#4. - Smallstep: make small-step semantics more polymorphic in the type of the global environment. - Globalenvs: introduce Senv.t (symbol environments) as a restricted view on Genv.t (full global environments). - Events, Smallstep: use Senv instead of Genv to talk about global names.
