Andrew Trick 3d957c0ead Further generalize this scheduler test. 
The order of copies depends on queue order, which is not very stable.

Andrew Trick e833e1cd6e MI-Sched: schedule physreg copies. 
The register allocator expects minimal physreg live ranges. Schedule
physreg copies accordingly. This is slightly tricky when they occur in
the middle of the scheduling region. For now, this is handled by
rescheduling the copy when its associated instruction is
scheduled. Eventually we may instead bundle them, but only if we can
preserve the bundles as parallel copies during regalloc.
