Fix a serious bug.
When initialized, the index of the ElementRegion was unsigned. But the index
value of the ArraySubscriptExpr is signed. This inconsistency caused the value
of the array element retrieved to be UnknownVal despite it was initialized to
symbolic.
This is only a hack. Real fix of this problem is required.

Enable the GRStateManager to do something when we finish a path. For example,
the ConstraintManager can print its internal state before its solver instance is
destroyed.

- Creator function pointers are saved in ManagerRegistry.
- The Register* class is used to notify ManagerRegistry new module is
available.
- AnalysisManager queries ManagerRegistry for configurable module. Then it
passes them to GRExprEngine, in turn to GRStateManager.

Add implicit conversions for Objective-C qualified ids, e.g.,
id<P0>
The intended overloading behavior of these entities isn't entirely
clear, and GCC seems to have some strange limitations (e.g., the
inability to overload on id<P0> vs. id<P1>). We'll want to revisit
these semantics and determine just how Objective-C++ overloading
should really work.

- Enhance PTH generation to write out IdentifierInfo table in two parts:
- a table including the IdentifierInfo data
- an index from persistent IdentifierInfo IDs to indices within this file.

Implement implicit conversions for Objective-C specific types, e.g.,
converting a pointer to one Objective-C interface into a pointer to another
Objective-C interface, and conversions with 'id'. The semantics seems
to match GCC, although they seem somewhat ad hoc.
Fixed a few cases where we assumed the C++ definition of isObjectType,
but were getting the C definition, causing failures in trouble with
conversions to void pointers.
-Change Parser::ParseCXXScopeSpecifier to MaybeParseCXXScopeSpecifier
-Remove Parser::isTokenCXXScopeSpecifier and fold it into MaybeParseCXXScopeSpecifier
-Rename Parser::TryAnnotateScopeToken to TryAnnotateCXXScopeToken and only allow it to be called when in C++
Add an overload for operator<<(const DiagnosticBuilder &DB,bool I).
Fixes building error on MSVC where passing bool couldn't resolve to one of the overloads.
Set default property attributes on each property.
Implemented anonymous category (also know as continuation class)
used to override main class's property attribute. This is work in
propgress.

Add support for AllocaRegion extent with GDM.
One design problem that is emerging is the signed-ness problem during static
analysis. Many unsigned value have to be converted into signed value because
it partipates in operations with signed values.
On the other hand, we cannot blindly make all values occuring in static analysis
signed, because we do have cases where unsignedness is required, for example,
integer overflow detection.

Convert IdentifierInfo's to be printed the same as DeclarationNames

effects and requires tweaking to a whole lot of code. This causes
a regression in two tests (xfailed) by causing it to emit things like:
Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')
instead of:
Line 10: duplicate interface declaration for category 'MyClass1(Category1)'
I will fix this in a follow-up commit.
As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency. This is good, but I was planning to do this
as an independent patch. There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.
