compiler.cfg.*: new word for consuming deques slurp/replenish-deque
...
most uses of slurp-deque processes one item and pushes a sequence of
items to continue working with. it can be formalized into a
slurp/replenish-deque combinator which also reduces the amount of
variables you need to use

compiler.cfg.liveness: refactoring so that words that doesn't modify

the live-set doesnt return it
e.g it's clearer when the effect is ( live-set insn -- ) than ( live-set insn -- live-set ) that the live-set is modified in place

compiler.cfg.liveness: Break the infinite loop--add the base-pointer as f to start with, and replace it with the real one if there's not a circular chain. Fixes #22 again.

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

Various codegen improvements:
...
- new-insn word to construct instructions
- cache RPO in the CFG
- re-organize low-level optimizer so that MR is built after register allocation
- register allocation now stores instruction numbers in the instructions themselves
- split defs-vregs into defs-vregs and temp-vregs
