12422 RS6000_BTI_bool_V16QI. Remove erroneous ALTIVEC_BUILTIN_VEC_CMPNE
12423 entry for overloaded function argument types RS6000_BTI_bool_V4SI
12424 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
12425 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
12426 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
12427 Power9 for implementations of vec_cmpne. Change the signature for
12428 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
12429 (representing vec_all_ne) to remove the previously described first
12430 argument of type RS6000_BTI_INTSI, as this was an artifact of
12431 reliance on the AltiVec predicate framework, which is no longer
12432 used in the implementation of these functions. Add
12433 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
12434 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
12435 since, unlike the AltiVec predicate framework implementation, we
12436 do not share function descriptors between vec_alle and vec_anyeq.
