* Relax block ordering constraints Before `block.Next` had to follow `block.ListNext`, now it does not. Instead `CodeGenerator` will now emit the necessary jump instructions to ensure control flow. This makes control flow and block order modifications easier. It also eliminates some simple cases of redundant branches. * Set PPTC version
