2840 instrumented. Simplify the logic by putting all the statements
2841 instrument 'base + len' inside a sequence, and then insert that
2842 sequence right before the current insertion point. Then, to
2843 instrument 'base + len', just get an iterator on that statement.
2844 And do not forget to update the pointer to iterator the function
2845 received as argument.
