[PowerPC] Add a peephole post RA to transform the inst that fed by add
...
If the arch is P8, we will select XFLOAD to load the floating point, and then, expand it to vsx and non-vsx X-form instruction post RA. This patch is trying to convert the X-form to D-form if it meets the requirement that one operand of the x-form inst is the special Zero register, and another operand fed by add inst. i.e.
y = add imm, reg
LFDX. 0, y
-->
LFD imm(reg)

If the arch is P9, we will select the DFLOADf32/DFLOADf64 pseudo instruction when we are loading a floating,

and expand it post RA basing on the register pressure. However, we miss to do the add-imm peephole for these pseudo instruction.
