This change matters only in case of MANUAL_VDB mode.

* finalize.c (GC_grow_table, GC_register_disappearing_link,
GC_unregister_disappearing_link_inner, GC_process_togglerefs,
GC_toggleref_add, GC_move_disappearing_link_inner,
GC_register_finalizer_inner, ITERATE_DL_HASHTBL_END,
DELETE_DL_HASHTBL_ENTRY, GC_finalize, GC_enqueue_all_finalizers): Call
GC_dirty where needed.
* gcj_mlc.c [GC_GCJ_SUPPORT] (GC_gcj_malloc, GC_debug_gcj_malloc,
GC_gcj_malloc_ignore_off_page): Likewise.

* include/gc_inline.h (GC_FAST_MALLOC_GRANS): Call
GC_end_stubborn_change(my_fl) after GC_FAST_M_AO_STORE() call unless
kind is GC_I_PTRFREE.
* include/gc_inline.h (GC_CONS): Call GC_end_stubborn_change(result).
