2360 For movsf, order stores so the VSX stores occur before the GPR
2361 store which encourages the register allocator to use a traditional
2362 FPR instead of a GPR. For movsd, order the stores so that the GPR
2363 store comes before the VSX stores to allow the power6 to work.
2364 This is due to the power6 not having a 32-bit integer store
2365 instruction from a FPR.
