merge revision(s) 60980,60984: [Backport #14070]
Modules should not have subclasses. When refining a module, the module was set to the superclass of its refinement, and a segmentation fault occurred. The superclass of the refinement should be an iclass of the module. [ruby-core:83617] [Bug #14070] The superclass of a refinement should have BasicObject as its ancestor. Otherwise, VM_ASSERT(callable_method_entry_p(cme)) in prepare_callable_method_entry() fails if VM_CHECK_MODE is 2. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_2_4@62233 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
