__wmemchr_avx2 uses vector compare and checks the elements of a vector
within boundary:

L(first_vec_x1_check):
        tzcntl  %eax, %eax
        /* Check the end of data.  */
        cmpq    %rax, %rdx
        jbe     L(zero)
        addq    $VEC_SIZE, %rax
        addq    %rdi, %rax
        VZEROUPPER
        ret
