ab0601d9 - Add PrunedLiveness::computeSSALiveness

Add PrunedLiveness::computeSSALiveness Straighforward API to build pruned liveness from a single SSA value. This 3-line function allows PrunedLiveness to be used anywhere ValueLifetimeAnalysis was used in OSSA form. Aside from simplicity and efficiency, the difference is that this composes with other utilities that only care about PrunedLiveBlocks, PrunedLiveness, or PrunesLivenessBounary independent of how those data structures were generated.
