Huh, indeed. I can repro. Not sure how to fix, but in digging around I found clang/test/codegen/integer-overflow.c.  Your newly added test file clang/test/CodeGen/integer-wrap.c is highly redundant of that. Why don't you remove clang/test/CodeGen/integer-wrap.c and simply add another RUN line to clang/test/codegen/integer-overflow.c?
