Fix scheduling undeterminism from sorting with DEBUG_INSNs
* haifa-sched.c (INSN_RFS_DEBUG_ORIG_ORDER): New access macro.
(rank_for_schedule_debug): Split from ...
(rank_for_schedule): ... this.
(ready_sort): Sort DEBUG_INSNs separately from normal INSNs.
* sched-int.h (struct _haifa_insn_data): New field rfs_debug_orig_order.
