90dda27a3a Bug correction in Schedule_interf 
Bug due to the fact that a variable can be "defined" and "read"
(in scheduling sense) by the same equation, without being a memory:
e.g., a clock defined as the result of a node application, together
with another result on this same clock.

Bug correction: basically removed the "assert false" on killed_vars,
decr_uses; do not count as "use" the self reads.

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

2956002f85 Correction and simplification of the sigali pass 
Added a "Contracts" pass, after inlining, taking care of the
contracts of the nodes called in the body of a node. This pass
"inlines" the code and assume/guarantee parts of these subcontracts.

The "Sigali" pass both generates the sigali ("z3z") code and add the call to
the controller (which is a node generated further by the sigali tool).
Therefore this pass has been included into the mls compiler, and removed
from the targets (a "z3z" dummy target has been kept for backward compatibility
reasons).

1e46c2a73c Makefile : removed target "all" from target "install" 
On some systems, the targets "all" and "install" must be
made with different rights. Then "all" cannot be a dependendy of
"install", especially since ocamlbuild try to read/modify some
files even if there is no compilation to perform.

Adrien Guatto
0abb050a23 Changed linear typing for merge. 
The new rule accepts that some branches of a linearly typed merge have linear
type Top, provided that at least one has type "lin". E.g.:

node f(x : int at r) returns (o : int at r)
var ck : bool;
let
  ck = true;
  o = merge ck (x whenot ck) 0;
tel

is now deemed valid.
