15969 support for predefined __POWER9_VECTOR__ macro to indicate that

15975 entry for overloaded function argument types RS6000_BTI_bool_V4SI
15976 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
15977 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
15978 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
15979 Power9 for implementations of vec_cmpne. Change the signature for
15980 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
15981 (representing vec_all_ne) to remove the previously described first
15982 argument of type RS6000_BTI_INTSI, as this was an artifact of
15983 reliance on the AltiVec predicate framework, which is no longer
15984 used in the implementation of these functions. Add
15985 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
15986 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
15987 since, unlike the AltiVec predicate framework implementation, we
