9590 For movsf, order stores so the VSX stores occur before the GPR
9591 store which encourages the register allocator to use a traditional
9592 FPR instead of a GPR. For movsd, order the stores so that the GPR
9593 store comes before the VSX stores to allow the power6 to work.
9594 This is due to the power6 not having a 32-bit integer store
9595 instruction from a FPR.
