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 flag represents that "this object is promoted at least once."
* gc.c, debug.c, object.c: catch up this change.

* .gdbinit (rp_id): show ID type.
* template/id.h.tmpl (ruby_id_types): make enum for debugger.

See this ticet about RGENGC.
* gc.c: Add several flags:
* RGENGC_DEBUG: if >0, then prints debug information.
* RGENGC_CHECK_MODE: if >0, add assertions.
* RGENGC_PROFILE: if >0, add profiling features.
check GC.stat and GC::Profiler.
* include/ruby/ruby.h: disable RGENGC by default (USE_RGENGC == 0).
* array.c: add write barriers for T_ARRAY and generate sunny objects.
* include/ruby/ruby.h (RARRAY_PTR_USE): added. Use this macro if
you want to access raw pointers. If you modify the contents which
pointer pointed, then you need to care write barrier.
* bignum.c, marshal.c, random.c: generate T_BIGNUM sunny objects.
* complex.c, include/ruby/ruby.h: add write barriers for T_COMPLEX
and generate sunny objects.
* rational.c (nurat_s_new_internal), include/ruby/ruby.h: add write
barriers for T_RATIONAL and generate sunny objects.
* internal.h: add write barriers for RBasic::klass.
* numeric.c (rb_float_new_in_heap): generate sunny T_FLOAT objects.
* object.c (rb_class_allocate_instance), range.c:
generate sunny T_OBJECT objects.
* string.c: add write barriers for T_STRING and generate sunny objects.
* variable.c: add write barriers for ivars.
* vm_insnhelper.c (vm_setivar): ditto.
* include/ruby/ruby.h, debug.c: use two flags
FL_WB_PROTECTED and FL_OLDGEN.
* node.h (NODE_FL_CREF_PUSHED_BY_EVAL, NODE_FL_CREF_OMOD_SHARED):
move flag bits.

Debugging/profiling features will be located.
* vm_trace.c: expose C-level TracePoint APIs.
Note that they are experimental.
* vm_trace.c, include/ruby/debug.h: rename `rb_hook_flag_t'
to `rb_event_hook_flag_t'.
Macro names `RUBY_HOOK_FLAG_*' are also renamed to
`RUBY_EVENT_HOOK_FLAG_*'.
* debug.h, vm_debug.h: rename debug.h to vm_debug.h.
* common.mk: ditto.
* debug.c, main.c, vm_core.h: ditto.

* insnhelper.ci: added. this function includes all functions that
vm insns need.
* common.mk: ditto.
* insnhelper.h, vm.h, vm.c: move some declaration.
* gc.h: remove GC_CHECK() macro because GC.stress is more useful.
* compile.c, iseq.c, vm_dump: ditto.
* gc.h, thread.c: move a prototype decalaration.
* debug.c, debug.h: rename some functions.
* compile.h: ditto.

proc.c, vm.c, vm_macro.def, vm_macro.def, yarvcore.c, yarvcore.h,
debug.c, debug.h: merge half-baked-1.9 changes. The biggest change
is to change node structure around NODE_SCOPE, NODE_ARGS. Every
scope (method/class/block) has own NODE_SCOPE node and NODE_ARGS
represents more details of arguments information. I'll write a
document about detail of node structure.

moving definitions place, add/remove prototypes, deleting
unused variables and removing yarv.h.
This commit doesn't change any behavior of ruby/vm.
* yarv.h, common.mk: remove yarv.h (contents are moved to yarvcore.h).
* error.c, eval_intern.h: include yarvcore.h instead yarv.h
* rename some functions:
* debug.[ch]: debug_*() -> ruby_debug_*()
* iseq.c: iseq_*() -> rb_iseq_*(), ruby_iseq_disasm()
* iseq.c: node_name() -> ruby_node_name()
* vm.c: yarv_check_redefinition_opt_method() ->
rb_vm_check_redefinition_opt_method()
* some refactoring with checking -Wall.
* array.c: remove rb_ary_ptr() (unused) and remove unused
local variables.
* object.c: add a prototype of rb_mod_module_exec().
* eval_intern.h (ruby_cref): set it inline.
* eval_load.c (rb_load), yarvcore.c: yarv_load() -> rb_load_internal().
* parse.y: add a prototype of rb_parse_in_eval() (in eval.c).
* process.c: add a prototype of rb_thread_stop_timer_thread() (in thread.c).
* thread.c: remove raw_gets() function (unused) and fix some format
mismatch (format mismatchs have remained yet. this is todo).
* thread.c (rb_thread_wait_fd_rw): fix typo on label name.
* thread_pthread.ci: comment out codes with USE_THREAD_CACHE.
* vm.c (rb_svar, rb_backref_get, rb_backref_get,
rb_lastline_get, rb_lastline_set) : moved from yarvcore.c.
* vm.c (yarv_init_redefined_flag): add a prototype and rename
yarv_opt_method_table to vm_opt_method_table.
* vm.c (rb_thread_eval): moved from yarvcore.c.
