haifa-sched: fix autopref_rank_for_schedule comparator [PR109187]
Do not attempt to use a plain subtraction for generating a three-way
comparison result in autopref_rank_for_schedule qsort comparator, as
offsets are not restricted and subtraction may overflow. Open-code
a safe three-way comparison instead.
gcc/ChangeLog:
PR rtl-optimization/109187
* haifa-sched.cc (autopref_rank_for_schedule): Avoid use of overflowing
subtraction in three-way comparison.
gcc/testsuite/ChangeLog:
PR rtl-optimization/109187
* gcc.dg/pr109187.c: New test.
