Change operator<< for raw_ostream and NamedDecl to take a reference instead of a pointer.
...
Passing a pointer was a bad idea as it collides with the overload for void*.

Remove AnalysisContext::getLiveVariables(), and introduce a templatized mechanism to lazily create analyses that are attached to AnalysisContext objects.

[analyzer] Refactor PathDiagnosticLocation: Make PathDiagnosticLocation(SourceLocation...) private. Most of the effort here goes to making BugReport refer to a PathDiagnosticLocation instead of FullSourceLocation.
...
(Another step closer to the goal of having Diagnostics which can recover from invalid SourceLocations.)

Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at.

[analyzer] Overhaul how the static analyzer expects CFGs by forcing CFGs to be linearized only when used by the static analyzer. This required a rewrite of LiveVariables, and exposed a ton of subtle bugs.
...
The motivation of this large change is to drastically simplify the logic in ExprEngine going forward.
Some fallout is that the output of some BugReporterVisitors is not as accurate as before; those will
need to be fixed over time. There is also some possible performance regression as RemoveDeadBindings
will be called frequently; this can also be improved over time.

Automatic Reference Counting.

Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.
Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

Don't emit a dead store for '++' operations unless it occurs with a return statement. We've never seen any other cases that were real bugs.
