injections compose (Values, Memdata, Memory)
- Memory chunks: Mfloat64 now has alignment 8; introduced Mfloat64al32
that works like old Mfloat64 (i.e. has alignment 4); simplified
handling of memcpy builtin accordingly.

- Most RTL operators now evaluate to Some Vundef instead of None
when undefined behavior occurs.
- More aggressive instruction selection.
- "Bertotization" of pattern-matchings now implemented by a proper preprocessor.
- Cast optimization moved to cfrontend/Cminorgen; removed backend/CastOptim.

- In pointer values "Vptr b ofs", interpret "ofs" as an unsigned int.
(Fixes issue with wrong comparison of pointers across 0x8000_0000)
- Revised Stacking pass to not use negative SP offsets.
- Add pointer validity checks to Cminor ... Mach
to support the use of memory injections in Stacking.
- Cleaned up Stacklayout modules.
- IA32: improved code generation for Mgetparam.
- ARM: improved code generation for op-immediate instructions.

(May fail if float is too big to be converted.)

- Reload temporaries are marked as destroyed (set to Vundef) across
operations in the semantics of LTL, LTLin, Linear and Mach,
allowing Asmgen to reuse them.
- Added IA32 port.
- Cleaned up float conversions and axiomatization of floats.

- 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.

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 memory model with concrete representation of ints & floats,
and per-byte access permissions
- Revised Globalenvs implementation
- Matching changes in all languages and proofs.

Introduced Int.iwordsize and used it in place of "Int.repr 32" or
"Int.repr (Z_of_nat wordsize)".

- 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.

Started to merge the ARM code generator.
Started to add support for PowerPC/EABI.
Use ocamlbuild to construct executable from Caml files.
