merged revision(s) 37075,37076,37082,37083,37088: [Backport #7123]
* gc.c: Use the non-recursive marking instead of recursion. The
recursion marking of CRuby needs checking stack overflow and the
fail-safe system, but these systems not good at partial points,
for example, marking deep tree structures. [ruby-dev:46184]
[Feature #7095]
* configure.in (GC_MARK_STACKFRAME_WORD): removed. It's used by
checking stack overflow of marking.
* win32/Makefile.sub (GC_MARK_STACKFRAME_WORD): ditto.
* gc.c (free_stack_chunks): it is used only when per-VM object space
is enabled.
* gc.c (rb_objspace_call_finalizer): mark self-referencing finalizers
before run finalizers, to fix SEGV from btest on 32bit.
* gc.c (gc_mark_stacked_objects): extract from gc_marks().
* gc.c (rb_objspace_call_finalizer): call gc_mark_stacked_objects
at suitable point.
* gc.c (init_heap): call init_mark_stack before to allocate
altstack. This change avoid the stack overflow at the signal
handler on 32bit, but I don't understand reason... [Feature #7095]
