I find this unit is smaller and more focused: it involves less machinery than a LIT test, and it checks only one property. It would provide a better signal when fails, as compared to clang/test/Analysis/ctu/diag/invlist-wrong-format-late.cpp because it us more restricted, and it should be easier to debug.

I find it also shorter and more clear especially after

67de200d9a69 Shorter unit test

That being said, it is kind of redundant with invlist-wrong-format-late.cpp
Shall I drop this unit test or invlist-wrong-format-late.cpp to avoid redundant testing?
