12047 entry for overloaded function argument types RS6000_BTI_bool_V4SI
12048 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
12049 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
12050 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
12051 Power9 for implementations of vec_cmpne. Change the signature for
12052 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
12053 (representing vec_all_ne) to remove the previously described first
12054 argument of type RS6000_BTI_INTSI, as this was an artifact of
12055 reliance on the AltiVec predicate framework, which is no longer
12056 used in the implementation of these functions. Add
12057 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
12058 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
