        For movsf, order stores so the VSX stores occur before the GPR
        store which encourages the register allocator to use a traditional
        FPR instead of a GPR.  For movsd, order the stores so that the GPR
        store comes before the VSX stores to allow the power6 to work.
        This is due to the power6 not having a 32-bit integer store
        instruction from a FPR.
