Austin Clements 8f694f6661 Flatten the Frame tree. Now each function call produces a ... single frame and non-overlapping variables reuse frame slots. As a result, entering and exiting blocks no longer requires code execution, which means jumps across block boundaries should be doable now. Frame slot initialization happens at definition time now, instead of at frame creation time. As an added bonus, Scope's are now exclusively compile-time objects and we no longer need to specially track the function activation frame for access to out vars.
