Cexec: record names of rules used in every reduction.
Interp: print these rule names in -trace mode. Also: simplified the exploration in "-all" mode; give unique names to states.
Csem: fix name of reduction rule "red_call".

environments (type Genv.t). Use symbol environments instead of global environments for external functions (module Events).

Restrict pointer event values to public global names.
Update proofs accordingly. PowerPC and ARM need updating.

The previous translation (in SimplExpr) produced references to the
same temporary variable with two different types (bool and int),
which is not nice if we want to typecheck the generated Clight.
The new translation avoids this and also gets rid of the double
cast to bool then to int. The trick is to change Eparen
(in CompCert C expressions) to take two types: the type to which the
argument must be converted, and the type with which the resulting
expression is seen.

- Support single-precision floats as first-class values
- Introduce chunks Many32, Many64 and types Tany32, Tany64 to
support saving and restoring registers without knowing
the exact types (int/single/float) of their contents, just
their sizes.
- Memory model: generalize the opaque encoding of pointers to
apply to any value, not just pointers, if chunks Many32/Many64
are selected.
- More properties of FP arithmetic proved.

- 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.

- 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.

based on a posteriori validation using the Rideau-Leroy algorithm
2- support for 64-bit integer arithmetic (type "long long").

function definition, so that comparisons between function pointers
are correctly defined.
AST, Globalenvs, and many other files:
represent programs as a list of (function or variable) definitions
instead of two lists, one for functions and the other for variables.

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.

- 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.
