* gc.c (gc_before_heap_sweep): fix freelist management.
  After rb_gc_force_recycle() for a object blonging to heap->freelist,
  `heap->using_page->freelist' is not null.

	* gc.c (gc_before_heap_sweep): Restructure code to mean clearly.
	  heap->freelist is connected to end of list.

* gc.c (vm_malloc_increase): do gc_rest_sweep() before GC.
  gc_rest_sweep() can reduce malloc_increase, so try it before GC.
  Otherwise, malloc_increase can be less than malloc_limit at
  gc_before_sweep(). This means that re-calculation of malloc_limit
  may be wrong value.
