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.
Bootstrap and regtest ongoing on x86_64-unknown-linux-gnu.
I consider this part quite obvious, [2/2] will need some ideas.

* tree-vect-stmts.cc (vectorizable_simd_clone_call): Cost
the number of OMP SIMD calls number of vector stmts.
