4880 entry for overloaded function argument types RS6000_BTI_bool_V4SI

4882 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
4883 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
4884 Power9 for implementations of vec_cmpne. Change the signature for
4885 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
4886 (representing vec_all_ne) to remove the previously described first
4887 argument of type RS6000_BTI_INTSI, as this was an artifact of
4888 reliance on the AltiVec predicate framework, which is no longer
4889 used in the implementation of these functions. Add
4890 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
4891 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
