llvm-project/clang/test/Misc/diag-template-diffing.cpp
Richard Trieu e1a6a7d6d3 Fix crash in template type diffing. 
When the type being diffed is a type alias, and the orginal type is not a
templated type, then there will be no unsugared TemplateSpecializationType.
When this happens, exit early from the constructor.  Also add assertions to
the other iterator accessor to prevent the iterator from being used.
