Retroactively updates the Changelog for Eva and Ivette.

See merge request frama-c/frama-c!4175

- MR !4164: fixes interpretation of Eva annotations.
- MR !3993: allows comments in .ya automata files and specifications about
  floating-point variables. Also, Eva shows the name of enumeration tags
  instead of their integer values.
- MR !4147: ivette shows the status of uninitialized and escaping variables.
- MR !4151: better display of large integer sets.
- MR !4134: the values table can show the status of ACSL predicates, the values
  of C lvalues in these predicates, and the values of function parameters.
- MR !4098: fixes a soundness bug of the equality domain.
- MR !4065: fixes performances issues on programs with too many callsites.
- MR !4015: fixes the bitwise domain on big-endian architecture.
- MR !4046: better partitioning splits on ACSL predicates.

[Eva] octagons: octagons about pointers

See merge request frama-c/frama-c!4032

Uses faster but approximating functions for [join], [narrow] and [add]:
in resulting maps (m, i), the inverse map [i] may contain variables that do
not appear in [m]. Do not fail when this is the case.

Fixes performance issues: the initialization of large arrays or structures
can lead to a very large number of relations or intervals.

Also, do not infer intervals on volatile lvalues.

- Includes both direct and indirect dependencies of variables.
- Avoids using Base.SetLattice.project.
- Properly catches Not_found error when a variable is not in relation in the
  state.

Also fixes [get_var_bases] function on missing variables.
This function is called by [relate] according to the [Relations] map, which is
an over-approximation of the relations really inferred in the state — it can
contains variables that do not belong to the state, so [get_var_bases] should
not crash in that case.

(Outside of the Variable module, which still differentiates variables and
lvalues for now.)

Infers intervals about lvalues and not only variables.
Registers in deps variables and lvalues for which an interval is inferred.
