GRExprEngine/CFRefCount/GRSimpleVals: We don't do any special handling (yet) of vector types.  Add explicit checks that when we process integers that they really are scalars.

- Don't crash on vector types.
- Handle typedefs.

Update CFGStmtVisitor to recognize that ObjCForCollectionStmts are special block-level "expressions".

Add (preliminary) transfer function support for ObjCForCollectionStmt.  Still need to flesh out some logic.

When processing DeclStmt, use the new interface to StateManager::BindDecl.  Conjuring of symbols is now done in VisitDeclStmt.

- Rename SetSVal to BindLoc
- Add BindDecl
- Add BindExpr

GRState:
- Environment now binds to Stmt* instead of Expr*.  This is needed for processing ObjCForCollectionStmt (essentially the declaration of the the 'element' variable can have an SVal attached to it).
- BindDecl no longer accepts Expr* for the initialization value; use SVal* instead.

llvm-svn: 59152

StoreManager::BindDecl now takes an SVal* for the initialization value instead of an Expr* (which can be null).  Lazy symbolication of conjured symbols is now the sole responsibility of GRExprEngine.

llvm-svn: 59151

- Added support for ObjCForCollectionStmt
- Fixed bug where expression values would be always set to uninitialized when loops were involved

Introduce a single AST node SizeOfAlignOfExpr for all sizeof and alignof expressions, both of values and types.

Implement RegionStoreManager::RemoveDeadBindings(). This prunes several false warning caused by removal of symbolic constraints. Currently we just mark all symbols live. Further optimization for dead binding removal needed.

Print integer value instead of raw pointer. This is a hack to be fixed by migrating the output in analyzer to llvm::raw_ostream.

available, things get much simplified.

One addition is that CompoundLiteralExpr can appear both in rvalue and lvalue
context.

Add a new expression class, ObjCSuperExpr, to handle the Objective-C 'super'. Remove ObjCThis from PredefinedExpr

   sets the whole struct to Unknown. Then we cannot assume the V passed to
   BindStruct() is always a CompoundVal. When it is an UnknownVal, we call
   BindStructToVal(UnknownVal).

2. Change the signature of InitializeStructToUndefined() to BindStructToVal()
   to reuse the code.

Comment out invalid assertion.  I'm leaving it in the code for now as a reminder to produce a test case.

llvm-svn: 58510

Simplify interface. We can get canonical type from the base region directly. No need for an extra type argument.

etc more generic. For some targets, long may not be equal to pointer size. For
example: PIC16 has int as i16, ptr as i16 but long as i32.

Also fixed a few build warnings in assert() functions in CFRefCount.cpp,
CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp.
