class.c: check for malloc failures
* class.c (rb_class_subclass_add): use xmalloc * class.c (rb_module_add_to_subclasses_list): ditto * class.c (rb_class_remove_from_super_subclasses): use xfree * class.c (rb_class_remove_from_module_subclasses): ditto [Bug #9616] xmalloc does OOM checking and helps GC accounting when used with xfree. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@45302 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
