When RGENGC_CHECK_MODE >= 2, all minor marking, run normal minor
marking *and* major/full marking. After that, compare the results
and shows BUG if a object living with major/full marking but dead
with minor marking.
After detecting bugs, print references information.
(RGENGC_CHECK_MODE == 2, show references to dead object)
(RGENGC_CHECK_MODE == 3, show all references)

`GC.stress=(flag)' accepts integer to control behavior of GC.
See code for details. Of course, this feature is only for MRI.
You can debug RGenGC (WB) using `GC.stress = 1'.
Using this option, do minor marking at all possible places.
GC::STRESS_MINOR_MARK = 1 and GC::STRESS_LAZY_SWEEP = 2
seem good to add.

write barriers at callback function are too early.
All write barriers are executed after `st_update()'

WBs had located before creating reference between a klass
and constant value. It causes GC bug.
# pseudo code:
WB(klass, value); # WB and remember klass
st_insert(klass->const_table, const_id, value);
`st_insert()' can cause GC before inserting `value' and
forget `klass' from the remember set. After that, relationship
between `klass' and `value' are created with constant table.
Now, `value' can be young (shady) object and `klass' can be old
object, without remembering `klass' object.
At the next GC, old `klass' object will be skipped and
young (shady) `value' will be miss-collected. -> GC bug
Lesson: The place of a WB is important.
