Fix memory leaks and use a pool_allocator

	* gcc.c (record_temp_file): Release name string.
	* ifcvt.c (noce_convert_multiple_sets): Use auto_vec instead
	of vec.
	* lra-lives.c (free_live_range_list): Utilize
	lra_live_range_pool for allocation and deallocation.
	(create_live_range): Likewise.
	(copy_live_range): Likewise.
	(lra_merge_live_ranges): Likewise.
	(remove_some_program_points_and_update_live_ranges): Likewise.
	(lra_create_live_ranges_1): Release point_freq_vec that can
	be not freed from previous iteration of the function.
	* tree-eh.c (lower_try_finally_switch): Use auto_vec instead of
	vec.
	* tree-sra.c (sra_deinitialize): Release all vectors in
	base_access_vec.
	* tree-ssa-dom.c (free_dom_edge_info): Make the function extern.
	* tree-ssa-threadupdate.c (remove_ctrl_stmt_and_useless_edges):
	Release edge_info for a removed edge.
	(thread_through_all_blocks): Free region vector.
	* tree-ssa.h (free_dom_edge_info): Declare function extern.
