21462 not use the AltiVec predicate framework.

21474 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
21475 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
21476 Power9 for implementations of vec_cmpne. Change the signature for
21477 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
21478 (representing vec_all_ne) to remove the previously described first
21479 argument of type RS6000_BTI_INTSI, as this was an artifact of
21480 reliance on the AltiVec predicate framework, which is no longer
21481 used in the implementation of these functions. Add
21482 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
21483 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
