by grouping instances of the same type into arrays.

The rationale is to be able to generate for loops with iterators.

The previous code was working, but probably by chance.

Also fix a bug in Lic2soc.make_e2a_elt where some deps and some
actions were lost. Actually, this bug ought to be triggered only with
nested calls. So this affects only programs executed via the
-knc/-keep-nested-calls option. and -2c is not supposed to work in
conjunction with -knc ! Hence this fix does not fix anything. But
still it fixes potentially future code if I (or someone else) decide
to handle nested calls in the lic one day.

I've just switched to ocaml 4.02, and it works only on carlit because
of GLIC 2.14 is not installed on other machine.

also, add some missing files.

It generates C code that compile on at least one example.
