I think you should combine that diff and this one into a single patch, otherwise this patch is untestable.

Comment at: include/clang/AST/ASTContext.h:1492-1493
+  /// \brief Return the unique unsigned counterpart of 
+  /// "ptrdiff_t" integer type.
+  QualType getUnsignedPointerDiffType() const;
Wrap the comment, and you might want to refer to C11 as a justification for why this is needed.
