Matthew Flatt 0eeb18f4d8 Improve the bytecode optimizer's ability to simplify `letrec's ... to smaller `letrec' groups or even `let*'. The goal of the change is to avoid performance surprises when using internal definitions, especially when mixing experessions with definitions. It's a somewhat scary change. Besides the new transformation, the optimizer pass's coordinate system for `letrec' (and sometimes `let*') bindings changed. No standard benchmarks were harmed during the making of this optimization. (None were improved, either.)		2010-07-08 13:43:40 -06:00
