2012-08-17  Richard Guenther  <rguenther@suse.de>

	* tree-sra.c (modify_function): Free redirect_callers vector.
	* ipa-split.c (split_function): Free args_to_pass vector.
	* tree-vect-data-refs.c (vect_peeling_hash_get_lowest_cost): Free
	body_cost_vec properly.
	(vect_enhance_data_refs_alignment): Likewise.
	* tree-vect-stmts.c (vectorizable_operation): Do not pre-allocate
	vec_oprnds.
	(new_stmt_vec_info): Do not pre-allocate STMT_VINFO_SAME_ALIGN_REFS.
	* tree-vect-slp.c (vect_free_slp_instance): Free the instance.
	(vect_analyze_slp_instance): Free everything.
	(destroy_bb_vec_info): Free the SLP instances.
