In plugins pdg, scope and slicing, directly uses the Eva API instead of this
function.

The only remaining mention to <Db.From> is in <eva/register.ml>.
It looks like a circular dependency, but maybe we could tackle it later.

With the automatic generation of `terminates` clauses, there is no empty
function contract. Instead, we detect function specification without any
assigns clause, which is unsound for the Eva analysis.

supports pattern such as

```c
enum {
     TAG1 = 42,
     TAG2 = TAG1 << 3
};
```

In presence of the following pattern of code:

```c
struct S;
enum { t = 1 };
struct S { char[t]; };
```

-ast-diff will attempt to compare the use of `t` in the field declaration
before having visited the `enum` definition. Thus, we can't rely on an enumitem
being present in the correspondance table when looking for a correspondance.

- Cabs2cil.is_boolean_result returns true if the expression is of type _Bool
- use standard result instead of custom expression for cast of a boolean to _Bool

The name seems to imply that it will return Some for any constant integer expression,
not only for integer literals
