Fixes some tests when changing the @EVA_OPTIONS@ macros.
This also removes the summary display at the end of the analyses.

Relies on the computation of the mathematical complement of ival.

The new option -eva-auto-loop-unroll defines the maximum limit of automatic
loop unrolling.

Removes useless file main.idx

As it is currently unsound.

Relations are represented as [X±Y ∈ ival]. If the [ival] is too large and
represents all possible values from the type of X and Y, then the relation
is meaningless. Do not infer such relations.

Greatly improves the domain performances.

New boolean option -eva-octagons-through-calls to specify whether the octagons
are propagated through function calls.

Ensures that [Domain.filter `Pre] is only used on a set of bases such that
[Domain.relate bases] is included in [bases].

Only if a boolean [debug] is set.

[pretty] only prints the relations inferred by the octagons domain.
The new function [pretty_debug] also prints the intervals inferred by the domain
and the map of related variables.

Makes the join more precise.
