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.
