18030 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
18031 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
18032 Power9 for implementations of vec_cmpne. Change the signature for
18033 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
18034 (representing vec_all_ne) to remove the previously described first
18035 argument of type RS6000_BTI_INTSI, as this was an artifact of
18036 reliance on the AltiVec predicate framework, which is no longer
18037 used in the implementation of these functions. Add
18038 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
18039 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
