12059 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
12060 Power9 for implementations of vec_cmpne. Change the signature for
12061 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
12062 (representing vec_all_ne) to remove the previously described first
12063 argument of type RS6000_BTI_INTSI, as this was an artifact of
12064 reliance on the AltiVec predicate framework, which is no longer
12065 used in the implementation of these functions. Add

12067 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
