Basic: import SmallString<> into clang namespace

(I was going to fix the TODO about DenseMap too, but
that would break self-host right now. See PR11922.)

Basic: import OwningPtr<> into clang namespace

Move a method from IdentifierTable.h out of line and remove the SmallString include.

Fix all the transitive include users.

StaticAnalyzer: Move ObjC- and CXX-specific methods out of line so checkers that don't care about the language don't have to pull in all the headers.

Change references to 'const ProgramState *' to typedef 'ProgramStateRef'.

At this point this is largely cosmetic, but it opens the door to replace
ProgramStateRef with a smart pointer that more eagerly acts in the role
of reclaiming unused ProgramState objects.

Remove addTransition method since it's the same as generateNode. Maybe we should

generated)?

Static Analyzer Diagnostics: Kill the addVisitorCreator(callbackTy, void*) API in favor of addVisitor(BugReporterVisitor*).

1) Create a header file to expose the predefined visitors. And move the parent(BugReporterVisitor) there as well.

2) Remove the registerXXXVisitor functions - the Visitor constructors/getters can be used now to create the object. One exception is registerVarDeclsLastStore(), which registers more then one visitor, so make it static member of FindLastStoreBRVisitor.

3) Modify all the checkers to use the new API.

Remove EnhancedBugReport and RangedBugReport - pull all the extra functionality they provided into their parent BugReport. The only functional changes are: made getRanges() non const - it adds default range to Ranges if none are supplied, made getStmt() private, which was another FIXME.

ImplicitNullDerefEvent is when we dereferenced a location that may be null.
