- Remove ConstNotEq from GRState/GRStateManager (!= tracking uses GDM instead).
- GRStateManager now can book-keep "contexts" (e.g., factory objects) for uses
  with data elements stored into the GDM.
- Refactor pretty-printing of states to use GRState::Printer objects
  exclusively. This removed a huge amount of pretty-printing logic from
  GRExprEngine.

CFRefCount
- Simplified some API calls based on refinements to the GDM api.

of using CheckerState).

Removed CheckerState from GRState.

Added class GRStateRef which wraps GRState* and GRStateManager*. This is handy
for generating new states with a single handle.

Added member template set/get functions to GRStateRef/GRState/GRStateManager for
accessing the Generic Data Map.

Updated checker state printer interface to allow transfer functions to return an arbitrary number of GRState::Printers.

Add variadic addInstMethSummary() and refactored addPanicSummary() to use this method. (code reduction).
Misc. cleanups.

 - Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
 - Moved Sema::getCurMethodDecl() out of line (dependent on
   ObjCMethodDecl via dyn_cast).

* Move FormatError() from TextDiagnostic up to DiagClient, remove now  
  empty class TextDiagnostic
* Make DiagClient optional for Diagnostic

This fixes the following problems:

* -html-diags (and probably others) does now output the same set of  
  warnings as console clang does
* nothing crashes if one forgets to call setHeaderSearch() on  
  TextDiagnostic
* some code duplication is removed

Added AssumeSymGT, AssumeSymGE, AssumeSymLT, AssumeSymLE to add some minor improvements to path-sensitivity.  Right now we basically treat 'x > y' and 'x < y' as implying 'x != y', but this restriction will only inevitably apply to our must rudimentary value tracking component (we'll implement more advanced value reasoning later).

Added decl_iterator to DeclStmt to provide an abstract interface to iterate over the ScopedDecls of a DeclStmt.
Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead.  Will update other clients after additional testing.

Remove call to isSEL and isSEL itself since the call is dead (isObjCObjectPointerType() will never return true for selectors).

llvm-svn: 54034

Only warn about missing/incomplete -dealloc implementations when a class contains a non-SEL, non-IBOutlet ivar that references an ObjC object.

Use ASTContext::isObjCObjectPointerType() to check if an ivar is a reference to an Objective-C object.
