These cases were found by further work to remove support for debug info versioning. Common cleanups (other than changing the version info in the tag field) included adding the last parameter to compile_units (recently added for fission support) and other cases of trailing fields in lexical blocks, compile units, and subprograms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176834 91177308-0d34-0410-b5e6-96231b3b80d8
