[analyzer] Fix use-after-free in HandleTranslationUnit.
...
A patch by Dmitri Gribenko!
The attached patch fixes a use-after-free in AnalysisConsumer::HandleTranslationUnit. The problem is that
BugReporter's destructor runs after AnalysisManager has been already
deleted. The fix introduces a scope to force correct destruction
order.
A crash happens only when reports have been added in AnalysisConsumer::HandleTranslationUnit's BugReporter. We don't have such checkers in clang so no test.

[analyzer] Introduce "event" mechanism in CheckerManager.
...
A checker can register as receiver/listener of "events" (basically it registers a callback
with a function getting called with an argument of the event type) and other checkers can
register as "dispatchers" and can pass an event object to all the listeners.
This allows cooperation amongst checkers but with very loose coupling.
