compiler.cfg.*: detached the normalize-height and schedule-instructions passes
those stages cause uninitialized "holes" in the stacks which in turn
causes gc errors if stack underflows occur

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.

compiler.cfg: Major restructuring -- do not compute liveness before local optimization, and instead change local optimizations to be more permissive of undefined values. Now, liveness is only computed once, after phi elimination and before register allocation. This means liveness analysis does not need to take phi nodes into account and can now use the new compiler.cfg.dataflow-analysis framework
