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

Optimize a ##dispatch that is applied to the result of a ##sub-imm or ##add-imm; this eliminates an instruction from the common 1 fixnum-fast { ... } dispatch and 8 fixnum-fast { ... } dispatch code sequences appearing in generic word expansions
