4574 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
4575 Power9 for implementations of vec_cmpne. Change the signature for
4576 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
4577 (representing vec_all_ne) to remove the previously described first
4578 argument of type RS6000_BTI_INTSI, as this was an artifact of
4579 reliance on the AltiVec predicate framework, which is no longer
4580 used in the implementation of these functions. Add

4582 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
