Slava Pestov e04df76f60 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

Slava Pestov 1af3b8ed65 If a register is spilled and the reload location is also a copy, we chicken out and don't coalesce. This is suboptimal but it's not clear to me how to implement it cleanly, and SSA graph coloring will solve this problem eventually anyway 2008-11-04 00:32:56 -06:00
