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().

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().

RUBY_INTERNAL_EVENT_GC_ENTER and
RUBY_INTERNAL_EVENT_GC_EXIT.
When invoking GC process, GC_ENTER event is called.
When exiting from GC process, GC_EXIT event is called.
Incremental GC (incremental marking and lazy sweep) can call
these events many times.
For example (minor marking):
(1) GC_ENTER
- (2) GC_START (minor GC)
(minor marking)
- (3) GC_END_MARK
(start lazy sweep)
(4) GC_EXIT
(ruby process)
(5) GC_ENTER
(lazy sweep)
(6) GC_EXIT
(ruby process)
(... repeat (5), (6))
(7) GC_ENTER
(finish lazy sweep)
- (8) GC_END_SWEEP
(9) GC_EXIT
2nd example (incremental major marking):
(1) GC_ENTER
- (2) GC_START (minor GC)
(start incremental marking)
(3) GC_EXIT
(ruby process)
(4) GC_ENTER
(incremental marking)
(5) GC_EXIT
(ruby process)
(... repeat (4), (5))
(6) GC_ENTER
(finish incremental marking)
- (7) GC_END_MARK
(start lazy sweep)
(8) GC_EXIT
(ruby process)
(9) GC_ENTER
(lazy sweep)
(10) GC_EXIT
(ruby process)
(... repeat (9), (10))
(11) GC_ENTER
(finish lazy marking)
- (12) GC_STOP_SWEEP
(13) GC_EXIT
Thease internal events enable to measure GC pause time completely.

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.

fstrings refered by static symbols and pinned dynamic symbols
are registerd by rb_gc_register_mark_object().
frstring refered by dynamic symbols (not pinned symbols)
are refered from global_symbols.dsymbol_fstr_hash (Hash object).
Note that fstrings refered from dynamic symbols must live loger
than symbol objects themselves because rb_gc_free_dsymbol() uses
fstring to remove from symbol tables.
This is why we can not mark fstrings from dynamic symbols.
This technique reduces root objects for GC marking.
* gc.c (gc_mark_roots): ditto.
* internal.h: ditto.
