Slava Pestov 3a9922d161 Fix compiler errors 2009-06-01 03:00:10 -05:00
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 145b635eb6 More optimization intended to reduce compile time. Another 10% speedup on compiling empty PEG parser
- new map-flat combinator replaces usages of 'map flatten' in compiler
- compiler.tree.def-use.simplified uses an explicit accumulator instead of flatten
- compiler.tree.tuple-unboxing uses an explicit accumulator instead of flatten
- fix inlining regression from last time: custom inlining results would sometimes be discarded
- compiler.tree's 3each and 3map combinators rewritten to not use flip
- rewrite math.partial-dispatch without locals (purely stylistic, no performance increase)
- hand-optimize flip for common arrays-of-arrays case
- don't run escape analysis and tuple unboxing if there are no allocations in the IR
