Merge branch 'unstable' into lustrec-seal
Further restructuring:- arrow.ml* to define basic builder for arrow (node, name, ...)- machine_code_common similar to corelang but for machine_code (printers, some builders, ...)- machine_code restricted to the translatation from normalized nodes to machines
- Makefile: solved dependency problem when compiling include lusi- Renamed type declarations as lustre_types and machine_code_types
- Normalization parameters (alias and unfold_array) are now provided as parameter- program type renamed as program_t- Initiating the lustrev tool with dependencies to z3 and seal.
Conditional activation of machine type plugin. currently a little buggy. Shall be desactivated.
[general] large modification: added machine types, a second typing phase dealing with machine types (eg uint8) typing was transformed as a functor and parametrized by basic types (int/real/bool) it can also be applied multiple times on the same program
[main] node locals are now sorted according to their dependencies wrt clocks. The produced lustre node with types shall now be compilable
Moved stage1 in separate file: it is shared among binaries
