AnalyzerStatsChecker improvements:
- Use BlockEntrance rather than BlockEdge to bring in line with UnreachableCodeChecker. Fixes an issue where unreached blocks would still be counted as reachable. - Added warnings for all BlockAborted locations. This allows us to see where the analyzer stopped analyzing. llvm-svn: 115110
