re PR middle-end/56461 (GCC is leaking lots of memory) 

PR middle-end/56461
	* tree-vect-loop.c (destroy_loop_vec_info): For !clean_stmts, just
	set nbbs to 0 instead of having separate code path.
	(vect_analyze_loop_form): Call destroy_loop_vec_info with true
	instead of false as last argument if returning NULL.
