  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)

               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]
