* Added constant propagation and better variable liveness tracking to skslc.Gravatar Ethan Nicholas2017-01-19
| | | | | | | | | | | | | | | | | | This allows skslc to track the values of variables with constant values across multiple statements and replace variable references with constant values where appropriate. The improved liveness tracking allows skslc to realize that a variable is no longer alive if all references to it have been replaced. It is not yet doing much with this information; better dead code elimination is coming in a followup change.
