9122 For movsf, order stores so the VSX stores occur before the GPR
9123 store which encourages the register allocator to use a traditional
9124 FPR instead of a GPR. For movsd, order the stores so that the GPR
9125 store comes before the VSX stores to allow the power6 to work.
9126 This is due to the power6 not having a 32-bit integer store
9127 instruction from a FPR.
