    x86-64: Optimize load of all bits set into ZMM register [BZ #28252]

    Optimize loads of all bits set into ZMM register in AVX512 SVML codes
    by replacing

            vpbroadcastq .L_2il0floatpacket.16(%rip), %zmmX

    and

            vmovups   .L_2il0floatpacket.13(%rip), %zmmX

    with
            vpternlogd $0xff, %zmmX, %zmmX, %zmmX

    This fixes BZ #28252.
