ba7d42b0 - [PowerPC] Optimize vec_splats of small FP values on Power8/9 (#199538)

[PowerPC] Optimize vec_splats of small FP values on Power8/9 (#199538) Recognize small constant FP splats representable as integers and lower them to vspltisw + xvcvsxwdp/xvcvsxwsp on Power8/9, avoiding constant pool loads.
