* loop.h (struct loop_movables): New.

	(LOOP_MOVABLES): New.
	(struct loop_info): Add movables field.
	* loop.c (struct movables): Delete.  Replace all uses
	with struct loop_movables.
	(the_movables): Delete.  Replace all uses with movables
	field in loop_info.
	(loop_movables_add, loop_movables_free): New functions.
	(scan_loop): Use xmalloc instead of alloca for movables.
	Call loop_movables_free.
