compiler.cfg.*: fix stack effect of compiler passes in optimize-cfg
since they all modify the cfg in place, it is better if their stack
effect is ( cfg -- ) instead of ( cfg -- cfg' )

compiler.cfg: new system to track when results of analyses need to be recomputed (reverse post order, linear order, predecessors, dominance, loops). Passes can now call needs-predecessors, needs-dominance, needs-loops at the beginning, and cfg-changed, predecessors-changd at the end. Linearization order now takes loop nesting into account, and linear scan now uses linearization order instead of RPO.
