Preliminary Liveness tracking (#2218)
* #include an absolute path didn't work - because paths were taken to always be relative.
* WIP tracking liveness.
* Skeleton around adding liveness instructions.
* Calling into liveness tracking logic.
Adds live start to var insts.
* Liveness macros have initial output.
* Looking at different initialization scenarios.
* Some discussion around liveness.
* WIP for working out liveness end.
* WIP Updated liveness using use lists.
* Is now adding liveness information
* Some small fixes.
* WIP around liveness.
* Seems to output liveness correctly for current scenario.
* Tidy up liveness code.
* Update comment arounds liveness to current status.
* Small fixes to liveness test.
* Add support for call in liveness analysis.
* Improve liveness example with array access.
* Small updates to comments.
* Disable liveness test because inconsistencies with output on CI system.
* Fix some issues brought up in PR.
