patch 9.1.1783: ins_compl_leader() too far away from ins_compl_leader_len()

Problem:  ins_compl_leader() defined too far away from
          ins_compl_leader_len() (after 9.1.1781).
Solution: Move ins_compl_leader() just before ins_compl_leader_len().
          Add missing "static" to eval0_simple_funccal() definition.
          (zeertzjq).
