- Switch CompCert C / Clight AST of composite types (structs and unions)
from a structural representation to a nominal representation,
closer to concrete syntax.
- This avoids algorithmic inefficiencies due to the structural representation.
- Closes PR#4.
- Smallstep: make small-step semantics more polymorphic in the type of the
global environment.
- Globalenvs: introduce Senv.t (symbol environments) as a restricted view
on Genv.t (full global environments).
- Events, Smallstep: use Senv instead of Genv to talk about global names.

Use these constructor functions in C2C to rely less on the types produced
by the unverified elaborator.

Several definitions in Cutil and elsewhere were accessing the default
value of !Machine.config, before it is properly initialized in Driver.
Delay evaluation of these definitions, and initialize Machine.config
to nonsensical values so that lack of initialization is caught early
(e.g. in Cutil.find_matching_*_kind).
Also, following up on commit [3b8a094], don't use "wchar_t" typedef
to type wide string literals, even if this typedef is in scope.
The risk here is to hide an inconsistency between "wchar_t"'s definition
in standard headers and CompCert's built-in definition.

This is achieved by declaring these functions in C2C.ml, then
re-checking their declarations in the global environment during
the Selection pass.
In passing, the "hf" parameter for SelectLong functions was removed
and replaced by fixed identifiers corresponding to the actual names
of the helper functions.

Closes PR#13.
Also: give string literals type unsigned char [] or signed char []
depending on the machine configuration. (Instead of unsigned char [] before.)

(in CompCert C to Cminor, included)
- Translation of "switch" to decision trees or jumptables made generic
over the sizes of integers and moved to the Cminor->CminorSel pass
instead of CminorSel->RTL as before.
- CminorSel: add "exitexpr" to support the above.
- ValueDomain: more precise analysis of comparisons against an integer
literal. E.g. "x >=u 0" is always true.

- 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.

- 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.

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.
