Douglas Gregor 453b012513 Make sure to always check the result of 
SourceManager::getPresumedLoc(), so that we don't try to make use of
an invalid presumed location. Doing so can cause crashes.

Tom Care 2f0419e1f8 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.

Tom Care 4545b2df42 Added AnalyzerStatsChecker, a path sensitive check that reports visitation statistics about analysis. Running clang with the -analyzer-stats flag will emit warnings containing the information. We can then run a postanalysis script to take this data and give useful information about how much the analyzer missed in a project.
