[3/6] Avoid accounting for non-existent vector loop versioning

vect_analyze_loop_costing uses two profitability thresholds: a runtime one and a static compile-time one. The runtime one is simply the point at which the vector loop is cheaper than the scalar loop, while the static one also takes into account the cost of choosing between the scalar and vector lo
