    tree-optimization/125174 - cost OMP SIMD calls
    
    The following makes the target aware of OMP SIMD calls.  Scalar
    costing costs calls as scalar_stmt, so make sure to at least do
    this level of costing for the vector side.
    
            PR tree-optimization/125174
            * tree-vect-stmts.cc (vectorizable_simd_clone_call): Cost
            the number of OMP SIMD calls number of vector stmts.
