Fix a dreadful slip in InterpreterPrimitives>>primitiveIdentical.  In the one argument case the old implementation checked the receiver for being forwarded rather than the argument.  This means that the interpreter and/or the debugger will answer the wrong value for e.g. ObjectTest testBecomeForward pt3 == pt2.
