This reduces the struct from 256 (from 288) bytes on my x86-64
system, allowing the struct to fit cleanly into 4 cache lines
(if a malloc implementation allows it).

`flag' contains several categories of attributes and it makes us
confusion (at least, I had confused).
* rb_method_visibility_t (flags::visi)
* NOEX_UNDEF -> METHOD_VISI_UNDEF = 0
* NOEX_PUBLIC -> METHOD_VISI_PUBLIC = 1
* NOEX_PRIVATE -> METHOD_VISI_PRIVATE = 2
* NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
* NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
* NOEX_BASIC -> basic (flags::basic, 1 bit)
* NOEX_MODFUNC -> rb_scope_visibility_t in CREF
* NOEX_SUPER -> MISSING_SUPER (enum missing_reason)
* NOEX_VCALL -> MISSING_VCALL (enum missing_reason)
* NOEX_RESPONDS -> BOUND_RESPONDS (macro)
Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
Background:
I did not know what "NOEX" stands for.
I asked Matz (who made this name) and his answer was "Nothing".
"At first, it meant NO EXport (private), but the original
meaning was gone."
This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
scope visibility.
It has 3 method visibilities (public/private/protected)
and `module_function`.

memo->v1 and memo->v2 is WB protected values.
So use MEMO_V1/V2_SET() macros to set these values.
memo->u3 is ambiguous (sometimes a VALUE, sometimes an integer
value), so use gc_mark_maybe() in gc.c to mark it.
Rename NEW_MEMO() to MEMO_NEW().
Move MEMO_FOR and NEW_MEMO_FOF macros from node.h.
Export a rb_imemo_new() function for ext/ripper.
* node.h: remove NODE_MEMO.
* enum.c: catch up these change.
