* include/ruby/ruby.h: introduce new type T_IMEMO.

  T_IMEMO is Internal Memo type, internal use only.
  T_IMEMO has same purpose of NODE_MEMO.
  To insert T_IMEMO, type numbers are modified a little.
* internal.h: define struct RIMemo. Each RIMemo objects
  has imemo_type. We can observe it by the imemo_type() function.
* gc.c (rb_imemo_new): added.
* node.h: remove NODE_CREF and NEW_CREF().
* node.c (rb_gc_mark_node): ditto.
* vm.c (vm_cref_new): use rb_imem_new().
* vm_eval.c: ditto.
* vm_eval.c (eval_string_with_cref):
* vm_eval.c (rb_type_str):
* vm_insnhelper.c: use RIMemo objects for CREF.
* ext/objspace/objspace.c: support T_IMEMO.
