`TemplateArgumentLocInventIterator` default constructor should not exists
https://github.com/llvm/llvm-project/blob/3496927edcd0685807351ba88a7e2cfb006e1c0d/clang/lib/Sema/TreeTransform.h#L4742
 because it doesn't and couldn't initialize `Self` member that is reference:

Instantiation of this constructor is always a compile-time error. 

Please note, that I didn't run any tests, because cannot imagine situation where this constructor can be properly used. There's no new tests for this fix for the same reason.
