6707 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
6708 Power9 for implementations of vec_cmpne. Change the signature for
6709 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
6710 (representing vec_all_ne) to remove the previously described first
6711 argument of type RS6000_BTI_INTSI, as this was an artifact of
6712 reliance on the AltiVec predicate framework, which is no longer
6713 used in the implementation of these functions. Add
6714 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
6715 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
