[PATCH] tree-optimization/109747 - SLP cost of CTORs

The x86 backend looks at the SLP node passed to the add_stmt_cost hook when costing vec_construct, looking for elements that require a move from a GPR to a vector register and cost that. But since vect_prologue_cost_for_slp decomposes the cost for an external SLP node into individual pieces this c
