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: 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

- re-organize low-level optimizer so that MR is built after register allocation

add new basis/constants vocab; CONSTANT: foo bar is equivalent to : foo bar ; inline

update some usages of inline words
