12436 support for predefined __POWER9_VECTOR__ macro to indicate that
12437 Power9 instruction selection is enabled.

12439 ALTIVEC_BUILTIN_VEC_CMPNE entry for overloaded
12440 function argument types RS6000_BTI_bool_V16QI and

12442 entry for overloaded function argument types RS6000_BTI_bool_V4SI
12443 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
12444 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
12445 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
12446 Power9 for implementations of vec_cmpne. Change the signature for
12447 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
12448 (representing vec_all_ne) to remove the previously described first
12449 argument of type RS6000_BTI_INTSI, as this was an artifact of
12450 reliance on the AltiVec predicate framework, which is no longer
12451 used in the implementation of these functions. Add
12452 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
12453 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
12454 since, unlike the AltiVec predicate framework implementation, we
