Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say pseudo built-in types, since Sema still injects a typedef for recognition (i.e. they aren't truly built-ins from a parser perspective).

This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-).

This patch also adds Type::isObjCBuiltinType().

This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small.

More test cases revealed that the logic in StoreManager::InvalidateRegion() needs more finesse when handling the invalidation of pointers.  Pointers that were invalidated as integers could later cause problems for clients using them as pointers.  It is easier for us to model a symbolic value as a pointer rather than modeling a non-symbolic value as a pointer.

This patch causes:
- StoreManager::InvalidateRegion() to not used the casted type of a region if
  it would cause a pointer type to be invalidated as a non-pointer type.
- Pushes RegionStore::RetrieveElement() further by handling retrievals from
  symbolic arrays that have been invalidated.  This uses the new SymbolDerived
  construct that was recently introduced.
  
The result is that the failing test in misc-ps-region-store-x86_64.m now passes.
Both misc-ps-region-store-x86_64.m and misc-ps-region-store-i386.m contain a
test case that motivated this change.

SymbolDerived allows us to model symbolic values that are related to other
symbols via a region hierarchy. For example, SymbolDerived can be used to model
individual values of a symbolic array.

Enhance RegionStoreManager to handle 'Retrieve's from SymbolicRegions.  We do this by silently wrapping the region with an ElementRegion.  This fixes the failures in misc-ps-region-store.m.

Note: One day, it might be useful to consider adding this info to DeclGroup (as the comments in FunctionDecl/VarDecl suggest). For now, I think this works fine. I considered moving this to ValueDecl (a common ancestor of FunctionDecl/VarDecl/FieldDecl), however this would add overhead to EnumConstantDecl (which would burn memory and isn't necessary).

It iterates over all the redeclarations, regardless of the starting point. For example:

1) int f();
2) int f();
3) int f();

if you have the (2) FunctionDecl and call redecls_begin/redecls_end to iterate, you'll get this sequence:
(2)
(1)
(3)

The motivation to introduce this was that, previously, if (3) was a function definition,
and you called getBody() at (2), it would not return it, since getBody() iterated over the previous declarations only,
so it would only check (2) and (1).
