3dfbeffeb6 Added syntax for reachability and attractivity in contracts 
Contracts can now comprise a list of objectives (in any order).

One objective can be (e being a Boolean heptagon expression) :
- invariance, with the syntax "enforce e"
- reachability, "reachable e"
- attractivity, "attractive e"

a00620ca19 Fixed interference of fast memories

the whole step function when its clock is false.

8815a2cd03 Better handling of clocks in memalloc 
- We can do a better allocation if we take into
account 'when' in extvalues 
(test/good/memalloc_clocks.ept shows the
improvement)
- Fixed a bug with memalloc on records: if we 
translate:
o = { a with .f = u }
to
o = a; o.f = u
then we cannot share u and o.f

6e2e2a9f47 Fixed bug in interference computation 
To know the variables read by an equation, we should
only look at the clock of variables. Otherwise, 
there could be a problem for node calls that 
define new clocks.

06e997e0c8 Fix for -mall 
Do not share memories and outputs if they are not
arrays, as it might make the register allocation
by the C compiler less efficient.

04b8853a1d Added a new reinit operator 
It has type:
reinit: t at r * t -> t at r

It can be used to put a constant value in a 
location.

81947eca40 Made linearity field not optional 
This helped solve a few bugs with linear types,
for instance when using automata.
The intermediate code is not well-typed (wrt to
linear types only), after the encoding of automata.

fbfa6eda1a Add Ewhen to the minils ast, And clocking of iterators. 
Ewhen is now the only case of possible recursion for minils exps.
This add was motivated by equations like :
(y,z) = f(x) when c
This equation to be correctly normalized in minils before needed :
y',z' = f(x)
y = y' when c
z = z' when c
But this new variables where needless since the final translation of when c
is the identity.
