compiler.cfg.alias-analysis: optimize ##vm-field-ptr and ##alien-global instructions, and optimize out ##compare between values of different alias classes; this optimizes '[ [ >float ] bi@ [ + ] [ - ] 2bi eq? ]' down to an o-op and removes boxing from '[ [ >float ] bi@ [ + ] [ - ] 2bi = ]'

compiler.cfg: virtual registers are integers now, and representations are stored off to the side. Fix bug in representation selection that would manifest if a value was used as a float and a fixnum in different branches; cannot globally unbox float in this case

compiler.cfg.write-barrier: simplify a little bit. It doesn't need to do copy propagation, since its a separate pass now

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
