vect: Adjust vectorizable_load costing on VMAT_GATHER_SCATTER && gs_info.decl

This patch adds one extra argument cost_vec to function
vect_build_gather_load_calls, so that we can do costing
next to the tranform in vect_build_gather_load_calls.
For now, the implementation just follows the handlings in
vect_model_load_cost, it isn't so good, so placing one
FIXME for any further improvement.  This patch should not
cause any functional changes.

gcc/ChangeLog:

	* tree-vect-stmts.cc (vect_build_gather_load_calls): Add the handlings
	on costing with one extra argument cost_vec.
	(vectorizable_load): Adjust the call to vect_build_gather_load_calls.
	(vect_model_load_cost): Assert it won't get VMAT_GATHER_SCATTER with
	gs_info.decl set any more.
