Before this patch, gc_marks_step() marks (white -> grey) fixed
number objects. However, this strategy does not fit practical
cases, for example too slow to make progres.
This patch changes this strategy how many objects the
gc_marks_step() should handle.
We can estimate how many times gc_marks_step() is called during
this major marking (== C) with the free slot number in pooled
pages. We also can estimate the living object number (== L)
using last marked_slots value. We can solve this problem (how
many objects should be process in gc_marks_step()) by L/C.
* gc.c (rb_objspace_t): add rb_objspace_t::rincgc::pooled_sltos and
step_slots.

rb_objspace_t:🎏:during_incremental_marking is not defined
when GC_ENABLE_INCREMENTAL_MARK is 0.

make and register special exceptions.
* vm.c (rb_vm_mark): do not need to mark special exceptions
because they are registerd by rb_gc_register_mark_object().
* eval.c (Init_eval): use rb_vm_register_special_exception().
* gc.c (Init_GC): ditto.
* proc.c (Init_Proc): ditto.
* thread.c (Init_Thread): ditto.

This function is similar to rb_gc_mark_locations(), but not
conservertive.
* internal.h: ditto.
* vm.c (env_mark): use rb_gc_mark_values() because env values should
be Ruby VALUEs.

* gc.c (gc_mark): add gc_mark_ptr() to skip is_markable_object()
check. gc_mark_maybe() can use gc_mark_ptr() directly because
passed pointer is checked by is_pointer_to_heap().

error messages.

to make accesssing both parameters easy.
* gc.c (heap_get_freeobj): add LIKELY() hint.
* gc.c (heap_get_freeobj_from_next_freepage): ditto.
* gc.c (newobj_of): check both parameters at once for exceptional
case.

ruby_gc_stressfull macro.
Rename objspace->gc_stress to objspace->gc_stress_mode.
If objspace->gc_stress_mode is true (!nil and !false) then
ruby_gc_stressfull becomes TRUE.
ruby_gc_stressfull will speedup newobj_of() slightly.
* gc.c: initialize ruby_gc_stress(full|_mode) by gc_params.gc_stress
even if ENABLE_VM_OBJSPACE is false.

Please refer this ticket for details.
This change also introduces the following changes.
* Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
RBasic::flags (2 bit). Age == 3 objects become old objects.
* WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
* LONG_LIVED bitmap to represent living objects while minor GCs
It specifies (1) Old objects and (2) remembered shady objects.
* Introduce rb_objspace_t::marked_objects which counts marked
objects in current marking phase. marking count is needed to
introduce incremental marking.
* rename mark related function and sweep related function to
gc_(marks|sweep)_(start|finish|step|rest|continue).
* rename rgengc_report() to gc_report().
* Add obj_info() function to get cstr of object details.
* Add MEASURE_LINE() macro to measure execution time of specific line.
* and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.
* debug.c: catch up flag name changes.
* internal.h: add rb_gc_writebarrier_remember() instead of
rb_gc_writebarrier_remember_promoted().
* array.c (ary_memcpy0): use rb_gc_writebarrier_remember().
* array.c (rb_ary_modify): ditto.
* hash.c (rb_hash_keys): ditto.
* hash.c (rb_hash_values): ditto.
* object.c (init_copy): use rb_copy_wb_protected_attribute() because
FL_WB_PROTECTED is moved from RBasic::flags.
* test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes.

fault on RGENGC_CHECK_MODE >= 1 introduced by r47188.
