Austin Clements 709e75e3a1 Implement if, for (modulo ranges), break, continue, increment, ... and decrement. blockCompilers now form a tree the mimics the nesting of scopes and provide convenient ways to enter and exit scopes. blockCompilers also track the break and continue PC for the current block. The statement testing interface now works in lists of statements, which simplifies a bunch of things.
