    R600/SI: Fixup CopyToReg register class in PostprocessISelDAG()

    The CopyToReg nodes will sometimes try to copy a value from a VGPR to an
    SGPR.  This kind of copy is not possible, so we need to detect
    VGPR->SGPR copies and do something else.  The current strategy is to
    replace these copies with VGPR->VGPR copies and hope that all the users
    of CopyToReg can accept VGPRs as arguments.
