(option -funprototyped, on by default).
Error if call to vararg function and -fvararg-calls is off.

- 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.

- Also axiomatize the semantics of inline asm
- In Cexec, revised parameterization over do_external_function
- In Interp.ml, matching changes + suppression of Interp_ext.ml

- Define type "block" as "positive" instead of "Z".
- Strengthen mem_unchanged_on so that the permissions are identical,
instead of possibly increasing.
- Move mem_unchanged_on from Events to Memory.Mem.
- Define it in terms of mem_contents rather than in terms of Mem.load.
- ExportClight: try to name temporaries introduced by SimplExpr
- SimplExpr: avoid reusing temporaries between different functions,
instead, thread a single generator through all functions.

- instead, punch a hole for the retaddr in Mach stack frame and
fill this hole with the return address in the Asmgen proof.

- Alternate semantics for Clight where function parameters are temporaries,
not variables
- New pass SimplLocals that turns non-addressed local variables into
temporaries
- Simplified Csharpminor, Cshmgen and Cminorgen accordingly
- SimplExpr starts its temporaries above variable names, therefoe
Cminorgen no longer needs to encode variable names and temps names.
- Simplified Cminor parser & printer, as well as Errors, accordingly.
- New tool clightgen to produce Clight AST in Coq-parsable .v files.
- Removed side condition "return type is void" on rules skip_seq
in the semantics of CompCert C, Clight, C#minor, Cminor.
- Adapted RTLgenproof accordingly (now uses a memory extension).

instead of two lists, one for functions and the other for variables.

injections compose (Values, Memdata, Memory)

that works like old Mfloat64 (i.e. has alignment 4); simplified
handling of memcpy builtin accordingly.

- native treatment of volatile accesses in CompCert C's semantics
- translation of volatile accesses to built-ins in SimplExpr
- native treatment of struct assignment and passing struct parameter by value
- only passing struct result by value remains emulated
- in cparser, remove emulations that are no longer used
- added C99's type _Bool and used it to express || and && more efficiently.
