Context

2018-12-17
23:19		Integrate kbk-jumpthread: replace the node-by-node splitting with a single pass that identifies many threading opportunities and also reduces the number of splits. Eliminate the old nodesplit pass, and the renameTemps pass, which is no longer required. check-in: a934a75e1f user: kbk tags: trunk
23:13		result, returnCode, returnOptions must be split into FAIL and non-FAIL paths because the backend isn't prepared to deal with all combinations of FAIL + someOtherType. Closed-Leaf check-in: 94358b53ea user: kbk tags: kbk-jumpthread
22:08		Finish jump threading - actually do the block duplication and redirection of jumps. Add the logic for SSA deconstruction (required by jump threading) and make SSA construction work with the deconstructed result. check-in: a41b93130e user: kbk tags: notworking, kbk-jumpthread
