Add assertions about held lock for apply_to_each_object callers
(code refactoring of commit 5e6cc59b0)
* alloc.c (GC_stopped_mark, GC_finish_collection): Add assertion (at
the beginning of the function) that the allocation lock is held.
* backgraph.c [MAKE_BACK_GRAPH] (GC_build_back_graph,
GC_traverse_back_graph): Likewise.
* mark.c (GC_initiate_gc): Likewise.
* alloc.c (GC_stopped_mark): Remove comment about the held lock
(because there is an assertion about it).
