A single metadata will not span multiple lines. This also helps me with my script to automatic update the testing cases. A debug info testing case should have a llvm.dbg.cu. Do not use hard-coded id for debug nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189033 91177308-0d34-0410-b5e6-96231b3b80d8
