introduce RCLASS_CLONED flag for inline cache.
Methods on duplicated class/module refer same constant inline
cache (IC). Constant access lookup should be done for cloned
class/modules but inline cache doesn't check it.
To check it, this patch introduce new RCLASS_CLONED flag which
are set when if class/module is cloned (both orig and dst).
