* class.c (rb_include_class_new), eval.c (rb_using_refinement):
make classes/modules (who share method table) shady.
If module `a' and `b' shares method table m_tbl and new method
with iseq is added, then write barrier is applied only `a' or `b'.
To avoid this issue, shade such classes/modules.
* vm_method.c (rb_method_entry_make): add write barriers.
