Subject: * vm_core.h (rb_vm_defineclass_type_t),   compile.c
 (iseq_compile_each), insns.def (defineclass): change the   meaning of the
 third operand of defineclass as follows:     lower 3bits: the type of the
 defineclass                    0 = class, 1 = singleton class, 2 = module    
 4th bit: a flag represents whether the defineclass is scoped                0
 = not scoped (e.g., class Foo) 	       1 = scoped (e.g., class
 Bar::Baz)     5th bit: a flag represents whether the superclass is specified 
               0 = not specified (e.g., class Foo)                1 =
 specified (e.g., class Bar < Foo)   If the superclass is specified and is not
 a class, a TypeError   should be raised.  [ruby-dev:46747] [Bug #7572]

* test/ruby/test_class.rb: related test.
