This is ugly but ISO C++ doesn't allow direct casts.

[analyzer] Overhaul of checker registration in preparation for basic plugin support. Removes support for checker groups (we can add them back in later if we decide they are still useful), and -analyzer-checker-help output is a little worse for the time being (no packages).

them into the clang namespace.

[analyzer] For -analyzer-checker-help show all the info about groups, packages, and which packages/checkers are hidden.

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.

Intoduce '-analyzer-checker-help' flag which outputs a list of all available static analyzer checkers.

This is pretty basic for now, eventually checkers should be grouped according to package, hidden checkers should be indicated etc.

-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
	Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
	-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
 register them with the CheckerManager which will be the entry point for all checker-related functionality.

Currently only the self-initialization checker takes advantage of the new mechanism.
