- Ctypes: add useful functions on attributes; remove attrs in typeconv
(because attributes are meaningless on r-values)
- C2C: fixed missing or redundant Evalof
- Cop: ignore attributes in ptr + int and ptr - int (meaningless on r-values);
add sanity check between typeconv/classify_binarith and the C99 standard.
- cparser: fixed several cases where incorrect type annotations were put
on expressions.

Elab: Handle C99 designated initializers.
C2C, Initializers: more precise intermediate AST for initializers.

Cutil.ml: fix sizeof calculation of structs.

- C function types and Cminor signatures annotated by calling conventions.
esp. vararg / not vararg
- Cshmgen: generate correct code for function call where there are
more arguments than listed in the function prototype. This is
still undefined behavior according to the formal semantics,
but correct code is generated.
- C2C, */PrintAsm.ml: remove "printf$iif" hack.
- powerpc/, checklink/: don't generate stubs for variadic functions.

- 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.
