  Log:
    * 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.
