compiler.tree.propagation: be more careful with intervals, ensuring that the inferred interval of a value is a subset of the value class's interval. This improves accuracy, for example [ >fixnum 1 + >fixnum most-positive-fixnum <= ] constant-folds to true

compiler.tree.escape-analysis: if the output of an #introduce node has an immutable tuple class type declaration, and it is not passed to any subroutine calls, or returned from the word, then unbox it. This speeds up vector arithmetic words on specialized arrays, because the specialized array is unboxed up-front, eliminating an indirection on every loop iteration

compiler.cfg: new system to track when results of analyses need to be recomputed (reverse post order, linear order, predecessors, dominance, loops). Passes can now call needs-predecessors, needs-dominance, needs-loops at the beginning, and cfg-changed, predecessors-changd at the end. Linearization order now takes loop nesting into account, and linear scan now uses linearization order instead of RPO.

compiler.cfg: convert code into two-operand form before SSA destruction; SSA destruction now operates on a relaxed SSA form where multiple defs of the same vreg are allowed, but only within a single basic block. This makes linear scan's coalescing redundant, allowing it to be removed completely
