This checker was created by Jim Goodnow II, and I migrated it to the
new Checker interface (recent changes by Argiris).

extending the existing support for sizeof and alignof.  Original
patch by Guy Benyei.

Make the Objective-C checker look for subclasses of NSString instead of just NSString and NSMutableString.

conventional categories into Basic and AST.  Update the self-init checker
to use this logic;  CFRefCountChecker is complicated enough that I didn't
want to touch it.

In preparation for fixing PR 6884, rework CFGElement to have getAs<> return pointers instead of fresh CFGElements.

- Also, consoldiate getDtorKind() and getKind() into one "kind".
- Add empty getDestructorDecl() method to CFGImplicitDtor.

They cooperate in that NSErrorChecker listens for ImplicitNullDerefEvent events that
DereferenceChecker can dispatch.
ImplicitNullDerefEvent is when we dereferenced a location that may be null.

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.

llvm-svn: 126454

[analyzer] Remove '-analyzer-experimental-internal-checks' flag, it doesn't have any checkers associated with it anymore.

llvm-svn: 126440

For example, if 'core.experimental.UnreachableCode' is hidden, it should not be enabled with 'core.experimental'.
Note that this requires llvm commit r126436.
