* fix namespace issue on singleton class expressions. [Bug #10943]

* vm_core.h, method.h: remove rb_iseq_t::cref_stack. CREF is stored
  to rb_method_definition_t::body.iseq_body.cref.
* vm_insnhelper.c: modify SVAR usage.
  When calling ISEQ type method, push CREF information onto method
  frame, SVAR located place. Before this fix, SVAR is simply nil.
  After this patch, CREF (or NULL == Qfalse for not iseq methods)
  is stored at the method invocation.
  When SVAR is requierd, then put NODE_IF onto SVAR location,
  and NDOE_IF::nd_reserved points CREF itself.
* vm.c (vm_cref_new, vm_cref_dump, vm_cref_new_toplevel): added.
* vm_insnhelper.c (vm_push_frame): accept CREF.
* method.h, vm_method.c (rb_add_method_iseq): added. This function
  accepts iseq and CREF.
* class.c (clone_method): use rb_add_method_iseq().
* gc.c (mark_method_entry): mark method_entry::body.iseq_body.cref.
* iseq.c: remove CREF related codes.
* insns.def (getinlinecache/setinlinecache): CREF should be cache key
  because a different CREF has a different namespace.
* node.c (rb_gc_mark_node): mark NODE_IF::nd_reserved for SVAR.
* proc.c: catch up changes.
* struct.c: ditto.
* insns.def: ditto.
* vm_args.c (raise_argument_error): ditto.
* vm_eval.c: ditto.
* test/ruby/test_class.rb: add a test.
