    omp-simd-clone: Unbreak bootstrap
    
    This patch fixes -Werror=sign-compare errors during stage2/stage3.

                Jakub Jelinek  <jakub@redhat.com>
    
            * omp-simd-clone.cc (simd_clone_adjust_return_type,
            simd_clone_adjust_argument_types): Use known_eq (veclen, 0U)
            instead of known_eq (veclen, 0) to avoid -Wsign-compare warnings.
    
    (cherry picked from commit 437bde93dcde8309bb23ee255924c697e8e70df9)
