  Log Message:
  -----------
  [SLP]Check only instructions with unique parent instruction user

Need to re-check the instruction with the non-schedulable parent, only
if this parent has a user phi node (i.e. it is used only outside the
  block) and the user instruction has unique parent instruction.
