* internal.h, vm_insnhelper.h: move definition `struct SVAR'
from vm_insnhelper.h to internal.h. And rename it to strcut vm_svar.
new imemo_type imemo_svar is added.

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.

rb_cref_t is data type of CREF. Now, the body is still NODE.
It is easy to understand what is CREF and what is pure NODE.

* 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.

keyword argument is required

"init arguments (p)" of compile.c indicates a Ruby code that
evaluates multiple assignments that is in method or block
parameters: def foo((m1,m2), (m3,m4), *r, (p1,p2), (p3,p4)); end
The former (init arguments (m)) evaluates the multiple assignments
before rest argument, that are (m1,m2) and (m3,m4). The letter
(init arguments (p)) does ones after rest argument, that are
(p1,p2) and (p3, p4).

implemented. [ruby-dev:39853]
* ruby.c: --dump=parsetree and --dump=parsetree_with_comment options
added. This is just for debug or research purpose. Note that the
compatibility of these options are not supported at all.
