re PR rtl-optimization/6405 (Loop-unrolling related performance regressions)

PR optimization/6405
* unroll.c (loop_iterations): last_loop_insn should be the previous
non-note instruction before loop->end.
* loop.c (strength_reduce): The conditional jump is the last
non-note instruction before loop->end (as above).
