[Bug target/37394] [4.4 Regression] Segfault in ia64_variable_issue with -O -fschedule-insns2

The problem is IA64 has

void
ia64_optimization_options (int level ATTRIBUTE_UNUSED,
                           int size ATTRIBUTE_UNUSED)
{
  /* Disable the second machine independent scheduling pass and use one for the
     IA-64.  This needs to be here instead of in OVERRIDE_OPTIONS because this
     is done whenever the optimization is changed via #pragma GCC optimize or
     attribute((optimize(...))).  */
  ia64_flag_schedule_insns2 = flag_schedule_insns_after_reload;
  flag_schedule_insns_after_reload = 0;

We didn't handle "-O -fschedule-insns2" properly when after function
specific change. Michael, can you take a look at it?  Thanks.
