[Bug rtl-optimization/28019] register allocator does not reschedule for x86 imull

The solution is "don't do -fschedule-insns on x86".

Unless you first add heuristics in the scheduler to keep a better eye on
register pressure, and fix the many known bugs in scheduling for x86.

Yes, yes we know, this is the nth bug about this issue.
