* compile.c (NODE_CLASS, NODE_MODULE), insns.def (defineclass): raise
an exception when "class Foo::Bar" is evaluated and Foo::Bar is
private. To implement this, define_type of "defineclass" is added
so that the instruction can distinguish whether the class definition
is scoped (class Foo::Bar) or not (class Bar).
* test/ruby/test_class.rb (test_redefine_private_class),
test/ruby/test_module.rb
(test_define_module_under_private_constant): add tests for above.
