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.

This function creates internal use only array (which is completely
hided by ObjectSpace.each_object) with filling nil.
Otherwise, it can be incldues strange VALUEs.
* internal.h: added.
* node.h: use rb_ary_tmp_new_fill() for MEMO.

commented at permute0(). since `n >= r` here, buffer overflow
never happened, just reduce unnecessary allocation though.

ARY_SET() is same functionality of RARRAY_ASET(), but
it has an assertion (`ary' doesn't have shared array).

Shared arrays were WB-unprotected object because
sharing array can modify shared array's buffer
if it occupied shared array.
[sharing array (ary)] -> [shared array (shared)] -> <buff>
| A
+---------------------------------------+
write `buff' with WB(ary, &buff[i], obj)
-> if `ary' and `shared' are old, then only `ary'
will be remembered.
-> traverse from `ary'. But `shared' is old, so
that written `obj' is not marked.
It cause WB miss so that shared arrays were WB-unprotected.
(WB-unprotected objects are marked everytime if it is living)
This patch insert WB() for `shared' if it is needed.

array owner is promoted and a shared array is not promoted.
Now, shared array is WB-unprotected so that shared arrays are not
promoted. All objects referred from shared array should be marked
correctly.
[ruby-core:61919] [ruby-trunk - Bug #9718]
* test/ruby/test_array.rb: add a test for above.
