Committing a good chunk of the pre-register allocation live interval splitting pass. It's handling simple cases and appear to do good things. Next: avoid splitting an interval multiple times; renumber registers when possible; record stack slot live intervals for coloring; rematerialize defs when possible.

pointer-to-base. Also, add overload ranking for pointer conversions
(for both pointer-to-void and derived-to-base pointer conversions).

Note that we do not yet diagnose derived-to-base pointer conversion
errors that stem from ambiguous or inacessible base classes. These
aren't handled during overload resolution; rather, when the conversion
is actually used we go ahead and diagnose the error.

Update Xcode project.  We still get a link error, however, because of an LLVM library that isn't being linked in for CodeGen (will fix).

Warn about potentially leaked objects that are returned from methods whose names do not follow the Cocoa Memory Management guidelines.

LoopPass*.
 - Although less precise, this means they can be used in clients
   without RTTI (who would otherwise need to include LoopPass.h, which
   eventually includes things using dynamic_cast). This was the
   simplest solution that presented itself, but I am happy to use a
   better one if available.

Fix incorrect testing for the end of the both strings in CStrInCStrNoCase.  This could cause a read-out-of-bounds error if s2 is smaller than s1.

Restrict creation of OverloadedFunctionDecl only to C++ (it was getting used for invalid redeclarations on C).

Fix <rdar://problem/6311947> clang on xcode (regression): error: use of undeclared identifier 'expandedValue'.

Factored the QualTypeOrdering predicate into its own header
(TypeOrdering.h), now that it is used in two places.

Now that DeclRefExpr accepts a NamedDecl, use a DeclRefExpr for when a CXXFieldDecl is referenced inside a method.
