1476 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
1477 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
1478 Power9 for implementations of vec_cmpne. Change the signature for
1479 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
1480 (representing vec_all_ne) to remove the previously described first
1481 argument of type RS6000_BTI_INTSI, as this was an artifact of
1482 reliance on the AltiVec predicate framework, which is no longer
1483 used in the implementation of these functions. Add

1485 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
