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.
