Without using exceptions.

Avoids catching the exception in each case of the pattern matching,
and simplifies the implementation.

- renames [eval_tlval] into [eval_term_as_lval], as it evaluates a term.
- renames [eval_thost_toffset] into [eval_tlval], as it evaluates a term_lval,
  and uses it instead of the previous [eval_tlval] when evaluating a term_lval.

More specifically, do not warn if actual parameter has less `const` qualifiers
all along the type than formal (it was already handled for a `const` under
a single pointer, but not more). Of course, the reverse would still emit
a warning.

     Since Db.once are often registered in daemons

     It simplifies and is not really needed

This annotation sets the maximum number of subdivisions in the evaluation
of expressions at a given statement.

Overrides the global option -eva-subdivide-non-linear for the given functions.

Prerequisite for new options or annotations to configure more finely
the subdivisions.
In partition.ml, the subdivisions are disabled.
Other files always use the default value of subdivisions.
