ca5a5b4392 correct overeager CLP(ℤ) goal expansion
For instance, consider:

    t(X) :- X #= 1.

We *cannot* expand this to:

    ?- listing(t/1).
    t(A) :-
       (  integer(A) ->
          A=:=A
       ;  (  var(A) ->
             true
          ;  true,
             clpz:clpz_equal(A,A)
          )
       ).

Also, a new binding *must not* be dragged outside of disjunctions,
since the code may look for example like this:

        i(X) :-
            (   X #= 3
            ;   X #= 4
            ).

This commit fixes such issues, and still rewrites CLP(ℤ) expressions
as far as possible already at compilation time.

For example:

    n(X) :- X #= 1+3.

This is now compiled to (note that 1+3 is evaluated to 4):

    ?- listing(n/1).
    n(A) :-
       (  integer(A) ->
          A=:=4
       ;  (  var(A) ->
             A=4
          ;  B=4,
             clpz:clpz_equal(A,B)
          )
       ).

Ideally, it should be compiled to:

    n(4).

1dbadbfc35 enable goal expansion for CLP(ℤ) goals
Example:

    integer_successor(I0, I) :- I #= I0 + 1.

Yielding:

    ?- listing(integer_successor/2).
    integer_successor(A,B) :-
       (  integer(B) ->
          (  integer(A) ->
             B=:=A+1
          ;  C is B,
             clpz:clpz_equal(C,A+1)
          )
       ;  (  integer(A) ->
             (  var(B) ->
                B is A+1
             ;  C is A+1,
                clpz:clpz_equal(B,C)
             )
          ;  clpz:clpz_equal(B,A+1)
          )
       ).

Thus, fast low-level arithmetic is used whenever possible.
