Artyom Skrobov 27720765ed Reverting r214064 and r215650 while investigating a pesky performance regression 
llvm-svn: 218296

Artyom Skrobov a208a73390 Use the proper post-order traversal in LiveVariables analysis, 
to recover the performance after r214064.

Also sorts out the naming for PostOrderCFGView, ReversePostOrderCFGView,
BackwardDataflowWorklist and ForwardDataflowWorklist, to match the accepted
terminology.

Also unifies BackwardDataflowWorklist and ForwardDataflowWorklist to share
the "worklist for prioritization, post-order traversal for fallback" logic,
and to avoid repetitive sorting.

Also cleans up comments in the affected area.

Ted Kremenek 81ce1c8a99 Rename AnalysisContext to AnalysisDeclContext. Not only is this name more accurate, but it frees up the name AnalysisContext for other uses.
