    AArch64: Fix -Werror issue in aarch64_simd_clone_compute_vecsize_and_simdlen
    
    g:fcefc59befd396267b824c170b6a37acaf10874e introduced a new variable named
    arg_type which shadows the function scoped one.
    
    The function scoped one is now unused and so causes bootstrap to fail due to
    -Werror.
    
    This patch removes the unused variable.
