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.
