        * gcc.target/powerpc/vsu/vec-any-eq-10.c: Add scan-assembler
        directive to assure selection of proper bit using rlwinm insn.

        * config/rs6000/altivec.h (vec_all_ne): Under __cplusplus__ and
        __POWER9_VECTOR__ #ifdef control, change template definition to
        use Power9-specific built-in function.
        (vec_any_eq): Likewise.
        * config/rs6000/vector.md (vector_ae_v2di_p): Change the flag used
        to control outcomes from this test.
        (vector_ae_<mode>p): For VEC_F modes, likewise.
