Seems these previous test files for overflow were not actually enabled in the baseline. Because their suffixes fall outside the scope of the [test configuration](https://github.com/llvm/llvm-project/blob/main/llvm/test/tools/llvm-dwp/X86/lit.local.cfg#L4).

I've marked the test in this patch as UNSUPPORTED for now and have added the commands and results in the patch description.
