1419 0) statement, even for cases where either 'base' or 'base + len'
1420 are not instrumented -- because they have been previously
1421 instrumented. Simplify the logic by putting all the statements
1422 instrument 'base + len' inside a sequence, and then insert that
1423 sequence right before the current insertion point. Then, to
1424 instrument 'base + len', just get an iterator on that statement.
