-;;; This function is used to set the continuation for a node, and thus
-;;; determine what receives the value and what is evaluated next. If
-;;; the continuation has no block, then we make it be in the block
-;;; that the node is in. If the continuation heads its block, we end
-;;; our block and link it to that block. If the continuation is not
-;;; currently used, then we set the DERIVED-TYPE for the continuation
-;;; to that of the node, so that a little type propagation gets done.
