14208 support for predefined __POWER9_VECTOR__ macro to indicate that

14214 entry for overloaded function argument types RS6000_BTI_bool_V4SI
14215 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
14216 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
14217 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
14218 Power9 for implementations of vec_cmpne. Change the signature for
14219 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
14220 (representing vec_all_ne) to remove the previously described first
14221 argument of type RS6000_BTI_INTSI, as this was an artifact of
14222 reliance on the AltiVec predicate framework, which is no longer
14223 used in the implementation of these functions. Add
14224 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
14225 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
14226 since, unlike the AltiVec predicate framework implementation, we
14227 do not share function descriptors between vec_alle and vec_anyeq.
