   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.

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.

Implement load from struct region. Instead of returning an UnknownVal(), we create a CompoundVal by loading from each field of the struct.

Enhance path-sensitive return-of-stack-address check to print out the line number of a compound literal (whose address is being returned) instead of printing out the hex representation of the pointer address of the CompoundLiteralExpr.

Pretty-printing for SVals now mainly uses llvm::raw_ostream.  We have an adapter for std::ostream, but this will be removed in the future.

CompoundVal now uses an ImmutableList<SVal> to store its set of SVals.  This change was motivated by the need to allow state-splitting in GRExprEngine::VisitInitListExpr.  As a side-benefit, we no longer need to perform any copies of SVals when creating a CompoundSVal, and the profiling of CompoundSVal is now constant time.

Fix PR 2978 false positive for missing release in -dealloc of an ivar retained via a property and then released by assigning nil to that property:

The attached patch adds additional checks to -warn-objc-missing-dealloc. It checks that all ivars which are used in implementation of synthesized properties are either

a) released in dealloc if the property has retain" or "copy" attribute OR
b) not released in dealloc if the property has "assign" attribute
