* 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.

83aba04862 * include/ruby/ruby.h: constify RBasic::klass and add
RBASIC_CLASS(obj) macro which returns a class of `obj'.
  This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
* object.c: add new function rb_obj_reveal().
  This function reveal interal (hidden) object by rb_obj_hide().
  Note that do not change class before and after hiding.
  Only permitted example is:
  klass = RBASIC_CLASS(obj);
  rb_obj_hide(obj);
  ....
  rb_obj_reveal(obj, klass);
  TODO: API design. rb_obj_reveal() should be replaced with others.
  TODO: modify constified variables using cast may be harmful for
  compiler's analysis and optimizaton.
  Any idea to prohibt inserting RBasic::klass directly?
  If rename RBasic::klass and force to use RBASIC_CLASS(obj),
  then all codes such as `RBASIC(obj)->klass' will be
  compilation error. Is it acceptable? (We have similar
  experience at Ruby 1.9,
  for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
* internal.h: add some macros.
* RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal
  object.
* RBASIC_SET_CLASS(obj, cls) set RBasic::klass.
* RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS
  without write barrier (planned).
* RCLASS_SET_SUPER(a, b) set super class of a.
* array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c,
  file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c,
  parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c,
  string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c:
  Use above macros and functions to access RBasic::klass.
* ext/coverage/coverage.c, ext/readline/readline.c,
  ext/socket/ancdata.c, ext/socket/init.c,
* ext/zlib/zlib.c: ditto.

instead of using RARRAY_PTR().
