    A llvm/test/CodeGen/ARM/unschedule-reg-sequence.ll

  Log Message:
  [ScheduleDAG] Support REQ_SEQUENCE unscheduling

REG_SEQUENCE node requires special treatment during the
unscheduling because the node is untyped and neither its
class, nor cost could be retrieved the same way as for
typed nodes.
