GCC states that the 'aligned' attribute applied to typedefs can lower the
default type alignment (unlike with structs).

- Extend checking to more than just left-values.
- Add function in Cil to check only for frama_c_init_obj attribute (as formals
  should not be annotated with frama_c_mutable one).

When -eva-octagon-through-calls is enabled, fixes a crash on non-integer
formal parameters, on which no relation can be inferred.

Do not use ocamlgraph in the GUI (via ocamlgraph.dgraph or ocamlgraph_gtk)
when gtk3 is used, as it is only available in gtk2.

- also for the special case of formal parameters
- values gathered should now be consistent with the partial graph built
