Oh, sure. The diff of two-cus-from-same-file.ll shows it fairly
clearly, which is to say it's the same change as all the other test
files. It just wasn't failing on X86 for some reason - and I don't
really know why that is. (presumably a different codepath that didn't
assert on broken DICompileUnits)

(& then the other change I made was to the GDB 7.5 test suite in
clang-tests-external, to un-XFAIL the few cases this fixed)
