AST: add ef_inline flag to external functions.
Selection: recognize calls to inlined built-ins and inline them as Sbuiltin.
CminorSel to Asm: added Sbuiltin/Ibuiltin instruction.
PrintAsm: adapted expansion of builtins.
C2Clight: adapted detection of builtins.
Conventions: refactored in a machine-independent part (backend/Conventions)
  and a machine-dependent part (ARCH/SYS/Conventions1).

- Revised handling of volatile reads: the execution environment
  dictates the value read, via the trace of events.

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.

- In Cminor and below, removed pointer validity check in semantics of 
  comparisons, so that evaluation of expressions is independent of
  memory state.
- In Cminor and below, removed "alloc" instruction.
- Cleaned up commented-away parts.
