* Module Cerrors is now called Diagnostic and can be used in parts of CompCert other than cparser/
* Replaced eprintf error. Instead of having eprintf msg; exit 2 use the functions from the
Diagnostics module.
* Raise on error before calling external tools.
* Added diagnostics to clightgen.
* Fix error handling of AsmToJson.
* Cleanup error handling of Elab and C2C.
*The implementation of location printing (file & line) is simplified and correctly prints valid filenames with invalid lines.

The unused variable check now uses two passes. One to collect the
used variables and one to report the unused variables.
Futhermore attribute checks are extended to composite declaration.
Also the check is now performed after elaboration.

There should not be a single check place, since for example
unknonw attributes should be check after elaboration and other
simplifications.

The new module adds a function which is called during parse after
all C transformation have taken place for adding additional
checks. Currently only unknown attribute are checked.

Added a check for errors after the elab phases to avoid problems
in the transformations due to broken input programs.

Now each warning either has a name and can be turned on/off, made
into an error,etc. or is a warning that always will be triggered.
The message of the warnings are similar to the ones emited by
gcc/clang and all fit into one line.
Furthermore the diagnostics are now colored if colored output is
available.

On windows opening files in text mode can result in errors due to
non-windows compatible input. Thus open files only in binary mode.

Having the file in memory will help build an error message.
Also, this may be slightly faster.

was not parsed correctly:
typedef int a;
int f() {
for(int a; ;)
if(1);
a * x;
}
Additionnaly, I tried to add some comments in the pre-parser code,
especially for the different hacks used to solve various conflicts.

Added functions to add more information to the debuging interface,
like the struct layout with offsets, bitifiled layout and removed
the no longer needed mapping from stamp to atom.

unblocking; improve translation of bitfield initializers and compound literals.

transformations.

1) Revised division of labor between RTLtyping and Lineartyping:
- RTLtyping no longer keeps track of single-precision floats,
switches from subtype-based inference to unification-based inference.
- Unityping: new library for unification-based inference.
- Locations: don't normalize at assignment in a stack slot
- Allocation, Allocproof: simplify accordingly.
- Lineartyping: add inference of locations that contain
a single-precision float.
- Stackingproof: adapted accordingly.
This addresses a defect report whereas RTLtyping was rejecting code that used a RTL pseudoreg to hold both double- and single-precision floats (see test/regression/singlefloats.c).
This corresponds to commits 2435+2436 plus improvements in Lineartyping.
2) Add -dtimings option to measure compilation times.
Moved call to C parser from Elab to Parse, to make it easier to
measure parsing time independently of elaboration time.

- 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.

- 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.
