(abs<mode>2, VFP16_HW iterator): Likewise.
(andc<mode>2, VFP16_HW iterator): Likewise.
(neg_<fp16_names><mode>2): Likewise.
(abs_<fp16_names><mode>2): Likewise.
(fma<fp16_names><mode>4): Likewise.
(fms<fp16_names><mode>4): Likewise.
(nfma<fp16_names><mode>4): Likewise.
(nfms<fp16_names><mode>4): Likewise.
* config/rs6000/rs6000-protos.h (FP16_ABS_BINARY): Likewise.
(FP16_NEG_BINARY,): Likewise.
