Merge of branches/full-expr-4:

- Csyntax, Csem: source C language has side-effects within expressions,
  performs implicit casts, and has nondeterministic reduction semantics
  for expressions
- Cstrategy: deterministic red. sem. for the above
- Clight: the previous source C language, with pure expressions.
  Added: temporary variables + implicit casts.
- New pass SimplExpr to pull side-effects out of expressions
  (previously done in untrusted Caml code in cparser/)
- Csharpminor: added temporary variables to match Clight.
- Cminorgen: adapted, removed cast optimization (moved to back-end)
- CastOptim: RTL-level optimization of casts
- cparser: transformations Bitfields, StructByValue and StructAssign
  now work on non-simplified expressions
- Added pretty-printers for several intermediate languages,
  and matching -dxxx command-line flags.
