1423 (mov<mode>_hardfloat): Split into separate movsf and movsd pieces.
1424 For movsf, order stores so the VSX stores occur before the GPR
1425 store which encourages the register allocator to use a traditional
1426 FPR instead of a GPR. For movsd, order the stores so that the GPR
1427 store comes before the VSX stores to allow the power6 to work.
1428 This is due to the power6 not having a 32-bit integer store
1429 instruction from a FPR.
