"Change Set:		MoreWeakMsgSendFixes-nk
Date:			20 December 2002
Author:			Ned Konz

CS 5005u16-Events introduced a call to a method
isReceiverOrAnyArgumentGarbage in Object>>actionSequence that was only
understood (much later, after CS 5155WeakMessageSend2-nk-rw) by
WeakMessageSends and WeakActionSequences.

Unfortunately, if you had an ActionSequence or a MessageSend around in
an action map, this would break, as they don't understand
isReceiverOrAnyArgumentGarbage.

I removed this call from the methods in Object so that any action maps
that can answer asMinimalRepresentation will work.

This includes:
ActionSequence, WeakActionSequence, MessageSend (added), and
WeakMessageSend.
