Add new diff modes to template type diffing. Remove an old assertion that does not hold. It is possible for a template argument to be a declaration in one instantiation and an integer in another. Create two new diff kinds for these (decl vs int and int vs decl). llvm-svn: 257869

Update the %diff modifer to have an alternate string print when a template tree is selected. This will allow more flexibility when converting diagnostics to use template type diffing. Also updated the internal manual and test cases for correctly keeping the bold attribute and for tree printing. llvm-svn: 159463

Improve template diffing handling of default integer values. When the template argument is both default and value dependent, the expression retrieved for the default argument cannot be evaluated, thus never matching any argument value. To get the proper value, get the template argument from the desugared template specialization. Also, output the original expression to provide more information about the argument mismatch. llvm-svn: 177209
