This reverts commit r179840 with a fix to test/DebugInfo/two-cus-from-same-file.ll I'm not sure why that test only failed on ARM & MIPS and not X86 Linux, even though the debug info was clearly invalid on all of them, but this ought to fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179996 91177308-0d34-0410-b5e6-96231b3b80d8
