    jit: fix test-vector-* failures
    
    Fix failures seen on i686 due to relying on exact floating-point
    equality when testing results of vector division.
    
    gcc/testsuite/ChangeLog:
            * jit.dg/test-vector-rvalues.cc (check_div): Add specialization
            for v4f, to avoid relying on exact floating-point equality.
            * jit.dg/test-vector-types.cc (check_div): Likewise.
