[tbsaunde+gcc]

From: Trevor Saunders <tbsaunde+...@tbsaunde.org>

gcc/ChangeLog:

2016-09-06  Trevor Saunders  <tbsaunde+...@tbsaunde.org>

        * bb-reorder.c (fix_crossing_unconditional_branches): Make type
        of jump_insn rtx_jump_insn *.
        * reorg.c (steal_delay_list_from_target): Make type of insn
        rtx_jump_insn *.
        (follow_jumps): Make type of jump rtx_jump_insn *.
