Unify ctx_iterator/ctx_begin()/ctx_end() and iterator/begin()/end() so that a single iterator type is used for both traversing decls of the same declaration context *and* of the parent declaration contexts, depending on the value of the bool parameter 'LookInParentCtx' that is passed to IdentifierResolver::begin().

When in C++, make EnumConstant names hide tag names in the same scope, instead of colliding with them.

- Make sure ObjCIvarDecl propagates the bitfield width.
- RewriteObjC::SynthesizeIvarOffsetComputation(): Avoid using the __OFFSETOF__ mumbo jumbo for bitfields (since it isn't legal C). This fixes <rdar://problem/5986079> clang ObjC rewriter: bitfields and ivar access don't mix.

When checking for name collision between a tag and a previously defined namespace, the collision occured even when the tag was in a different nested scope.
Fix it by taking into account the scope when checking for namespace-tag name collisions.

Fix regression introduced by http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080714/006514.html.

The regression was the casts from integers to pointers where not being handled: they would just return UnknownVal.  This would greatly decrease path-sensitivity.

Fix transfer function logic in GRSimpleVals for integer casts: only support casts from integers to integers.
This fixes a crash reported by Anders Carlsson!

Added parsing/sema support for __attribute__ ((IBOutlet)), a clang-specific attribute that the static analyzer will use to recognize what ivars are IBOutlets.

isRetain() and isRelease() now only returns true if "Retain"/"Release" appears in the suffix of a function's name.

Add some code to handle vector comparisons, which is the language side
of the llvm vicmp/vfcmp instructions.  Also make the vector-vector and
vector-scalar asign checks a bit more sane under the presence of lax vector
conversions.

Refactored error reporting in CheckObjCDealloc and CheckObjCInstMethSignature to use this new bug reporting interface (major code simplification).

ObjCImplementationDecls and sees if a ancestor class defines a method with the
same selector but with a different type signature. Right now it just compares
return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.

Refactored auditor interface within GRExprEngine and GRCoreEngine to use a "batch auditor" to dispatch to specialized auditors instead of having a separate vector for each audited Expr*.  This not only provides a much cleaner implementation, but also allows us to install auditors for any expression.

current store implementation is now encapsulated by BasicStore.

These changes prompted some long due constification of ValueState. Much of the
diffs in this patch include adding "const" qualifiers.

Simplify the parser a bit by looking at the next token without consuming it (by Preprocessor::LookNext):

-Remove ParseExpressionWithLeadingIdentifier and ParseAssignmentExprWithLeadingIdentifier.
-Separate ParseLabeledStatement from ParseIdentifierStatement.
