New implementation for 'tbclist' - Fixes a bug, by removing dummy nodes together with the node itself. (The previous implementation could leave dummy nodes in frames which otherwise had no tbc variables, and therefore would not close variables; that could leave 'tbclist' pointing higher than 'top', which could dangle if the stack shrank.) - Computes MAXDELTA based on the type of delta, to ease changing its type if needed. - Instead of 'isdummy', uses 'delta==0' to signal dummy nodes. (Dummy nodes always have MAXDELTA for their real delta.)
