target.h (struct vectorize): Add new target builtin.

	* target.h (struct vectorize): Add new target builtin.
	* tree-vectorizer.c (destroy_loop_vec_info): Call
	vect_free_slp_instance instead of vect_free_slp_node.
	* tree-vectorizer.h (enum slp_load_perm_type): New.
	(struct _slp_instance): Add new fields.
	(SLP_INSTANCE_LOAD_PERMUTATION): New.
	(SLP_INSTANCE_LOADS): New.
	(vect_free_slp_tree): Remove.
	(vect_free_slp_instance): Declare.
	(SLP_TREE_LOADS_PERM_TYPE, TARG_VEC_PERMUTE_COST): New.
	(vectorizable_load): Add argument.
	(vect_transform_slp_perm_load): New.
	* tree-vect-analyze.c (vect_analyze_operations): Add an argument to
	vectorizable_load.
	(vect_get_place_in_interleaving_chain): New function.
	(vect_free_slp_tree): Make static.
	(vect_free_slp_instance): New function.
	(vect_build_slp_tree): Add new arguments. Allow load permutations and
	collect the load location in the interleaving chain.
	(vect_supported_slp_permutation_p): New function.
	(vect_supported_load_permutation_p): Likewise.
	(vect_analyze_slp_instance): In case of loads permutation, call
	vect_supported_load_permutation_p to check that the permutation is
	supported.
	* target-def.h (TARGET_VECTORIZE_BUILTIN_VEC_PERM): New.

	statements in the node if permutation is required. Call
	vect_transform_slp_perm_load to generate the permutation.
	(vect_transform_stmt): Add new argument. Call vectorizable_load with
	additional argument.
	(vect_schedule_slp_instance): In case of loads permutation, allocate
	vectorized statements structure for all the related SLP nodes. Call
	vect_transform_stmt with addditional argument.
	(vect_transform_loop): Call vect_transform_stmt with correct arguments.
	* config/spu/spu.c (spu_builtin_vec_perm): New.
	(TARGET_VECTORIZE_BUILTIN_VEC_PERM): Redefine.
